The hundred missing snes games update

As i'm sure a lot of you who follow emulation and general gaming heard about the missing snes games that were worth $10k were lost in post, and did make major news posts on emulation sites and gaming sites alike.
But today the panic is officially over.
Heres what byuu said:

On February 21st, I received an e-mail on the missing mail search I had submitted on January 30th, informing me that my package had been located!
Excited, I contacted my CA rep.
... who then proceeded to tell me that the search had failed, and that the e-mail notification was errant.
However, she promised to request all possible locations the package could have ended up at to do one last search.
Success again?
The CA rep called me late in the day advising that someone in the Atlanta, GA mail recovery center had just now located my package!
Thankfully, the photographs I took of the packages before sending back the first batch of 100 games proved useful with exact appearance, dimensions, weight, etc being available for the search team.
Still, given all the constant ups and downs, I wanted to wait until the package was in hand before giving anyone any false hope.
Success for real!
Finally, today, February 23rd, the ordeal is finally over!

Hopefully now the Snes preservation project can now continue without any more major mishaps.

SuperJarioES Released

Jason Ladere, author of Jario64 (N64 emulator), informed us about his new project - written in java SNES emulator - SuperJarioES. As you can see, for initial release, it works quite well.

Here's full info:

I have released the initial version of my snes emulator SuperJarioES which is based off of the higan/bsnes emulator. I have also released a newer version of my older Jario64 N64 emulator. Both of these emulators, along with my other emulators are built using a Fractal Component Architecture.

Visit official homepage at code goole for latest source s and binaries, and don't forget to leave your feedback at initial EmuTalk thread.

bsnes v088

bsnes is a Nintendo, Super Nintendo, and Game Boy Color emulator, that began development on 2004. It focuses on accuracy and clean code above all else. It never uses speed or compatibilty hacks. As a result, the minimum system requirements are greater than with other emulators.

Here're release notes for v088 :

As promised from the last news update, this release adds preliminary Game Boy Advance emulation. It's not perfect by any means, but it's one of the better first releases I've put out. It emulates all GBA functionality with the exception of the link cable and ROM prefetch buffer, although being a first release, there are bound to be plenty of bugs lurking in the core. I'd of course love some help with bugfixes, if anyone is interested =)

It's important to note that the GBA emulation has not been optimized yet. The GBA is a more demanding system than the SNES, by way of a much faster CPU core and higher frequency audio. You can expect about ~150fps on average with a Core i7-class CPU for now, but please note that I do intend to improve upon this performance in future releases.

For a bit of backstory: this is basically a byproduct of SNES ST018 emulation. This processor ended up using an ARMv3 CPU core. And since the GBA uses an ARMv4 CPU core, it seemed like a good choice: we could improve the ARM emulation for the ST018, and emulate the final 2D-based Nintendo system.

In the end, it turned out to be harder than expected: it took about a month to complete the emulation core, and it was only this quick due to extensive help from Cydrak; who fixed numerous CPU bugs, emulated the affine and bitmap rendering modes, and also implemented the new GBA FIFO audio channel, among other things.

On a side note, thanks to Cydrak and krom's hardware testing, we do have a nice milestone right out of the gate: proper OBJ mosaic emulation, which seems to be a first. At the very least, hopefully this will be helpful to other emulators.

Note that you will need the GBA BIOS image to use this. There will not be any high-level emulation of the BIOS functions for obvious reasons. Name the file "bios.rom", and place it inside the "Game Boy Advance.sys" folder.

bsnes v079.04

News via http://www.emucr.com/2011/06/bsnes-v07904.html

bsnes v079.04 is released. bsnes is an emulator for the Super Famicom and SNES video game systems. The purpose of the emulator is a bit different from other emulators: it focuses on accuracy, debugging functionality, and clean code.

bsnes v079.04 Changelog:

bsnes v079.04 - Cx4 LLE support2011-06-20
Back from vacation. We were successful in emulating the Cx4 using LLE during my vacation. We finished on June 15th. And now that I'm back, I've rewritten the code and merged it into bsnes official. With that, the very last HLE emulation code in bsnes has now been purged.

I still have some more plans for bsnes v080, so I'm not going to bump the version number just yet. Plus I would like it if we could thoroughly test the new Cx4 LLE support to ensure it is bug-free. To that aim, if you have some time and would like to help test: please download bsnes v079.04 and cx4.bin. Place cx4.bin in the same folder as "Mega Man X 2 (U).sfc" and "Mega Man X 3 (U).sfc", and then do your best to play through the entire games with no cheat codes, and uncover all of the secrets that you can.

If you find any bugs, or if the console window prints "invalid opcode" at any time, please send me a note on my forums. Thanks in advance to anyone who can help test this.

Well then, moving on ... all that's left is the ST-0018. Dr. Decapitator is currently busy with the N64 CIC, but after that we should hopefully make some progress in dumping its internal ROMs.

bsnes v078

News via AEP

byuu has released a new version of his SNES emulator bsnes.

bsnes v078 released (2011-04-30)

Finally, a new release. I have been very busy finishing up SNES box, cartridge and PCB scanning plus cataloguing the data, however this release still has some significant improvements.

Most notably would be randomization on startup. This will help match the behavior of real hardware and uninitialized memory + registers. It should help catch homebrew software that forgets to initialize things properly. Of course, I was not able to test the complete library, so it is possible that if I´ve randomized anything that should be constant, that this could cause a regression. You can disable this randomization for netplay or to work around any incompatibilities by editing bsnes.cfg and setting snes.random to false.

The GUI also received some updates. Widget sizes are now computed based on font sizes, giving it a perfectly native look (because it is native.) I´ve also added a hotkey remapping screen to the input settings. Not only can you remap inputs to controllers now, but those who did not know the hotkey bindings can now quickly see which ones exist and what they are mapped to.

Please enjoy.


memory and most registers are now randomly initialized on power-up

fixed auto joypad polling issue in Super Star Wars

fixed .nec and .rtc file extensions (they were missing the dot) [krom]

PPU/accuracy now clears overscan region on any frame when it is disabled

PPU/compatibility no longer auto-blends hires pixels (use NTSC filter for this)

added hotkey remapping dialog to input settings window

added a few new hotkeys, including quick-reset

phoenix API now auto-sizes widgets based on font sizes

file dialog once again remembers previously selected file when possible

updated mightymo´s cheat code database to April 19th release

bsnes 0.031 Released

New release posted. Perhaps the most important change was fixing a bug in the Windows port when the keyboard was used for input. For some reason, the IsDialogMessage() function I use for tab key support was causing the main window to emit the Windows error beep every time a key was pressed after a few minutes of use. I do not know why this is, so I have simply disabled the tab key support to prevent this from happening.

Other than that, lots of polishing went into this release. UPS soft-patching will work with the recently released Der Langrisser v1.02 translation, for those curious. You can also store the UPS patches in GZ/ZIP/JMA support, and bsnes will detect this and decompress the patches first. Use the same ".ups" file extension for this, as it detects via file header.

If you wish to try out the newly added OpenGL support: start bsnes, go to Settings->Configuration->Advanced and set system.video to "wgl" (or "glx" for Linux users), and then restart the emulator. Please bear in mind that ATI's OpenGL drivers are an industry-wide joke, so I'd only recommend trying this on an nVidia or Intel video card.

• Fixed bug and re-enabled HDMA bus sync delays
• Emulated newly discovered IRQ timing edge case
• Optimized offset-per-tile rendering
• Added state-machine implementation of S-DSP core, ~5% speedup
• Added SPC7110 detection, will now warn that this chip is unsupported
• Fixed very annoying Windows port OS beeping noise when using keyboard for input
• Linux port will now save most recent folder when no default ROM path is selected
• Added OpenGL rendering support to Windows port [krom]
• Fixed Direct3D pixel mode scaling bug [krom, sinamas, VG]
• Improved SNES controller graphic [FitzRoy]
• Added UPS (not IPS) soft-patching support; UPS patch must be made against unheadered ROM
• As always, cleaned up source code a bit

bsnes 0.030 Released

I didn't want to release a new version so soon, however there is a rather serious bug in bsnes v029 where the path information for the save RAM files is discarded when one has not selected a default save RAM / cheat path from the path settings tab in the configuration settings window. Because of this, it gets stored to the base directory. For Windows users, this is c:, and for Linux users, this is /

This bug forced my hand, so I'm releasing v030 to correct this issue. I also cleaned up the S-DSP emulation code to be more consistent with my programming style -- it gets bit-perfect matches to v029's wave output, so I don't foresee there being any problems.

bsnes 0.029 Released

A new version of bsnes has been released. It contains a few minor emulation fixes, as well as user interface improvements. Behind the scenes, the source has been cleaned up more in preparation for running the CPU and PPU (video processor) separately from each other (eg with no enslavement.) This is required for implementing a clock cycle based PPU renderer.

• Greatly improved invalid DMA transfer behavior, should be nearly perfect now
• Major code cleanup -- most importantly, almost all PPU timing-related settings moved back to PPU, from CPU
• Added option to auto-detect file type by inspecting file headers rather than file extensions
• Rewrote video filter system to move it out of the emulation core -- HQ2x and Scale2x will work even in hires and interlace modes now, 50% scanline filter added
• Re-added bsnes window icon
• Added new controller graphic when assigning joypad keys [FitzRoy]
• Redundant "Advanced" panel settings which can be configured via the GUI are no longer displayed
• Improved speed regulation settings
• XP and Vista themes will now apply to bsnes controls
• Added "Path Settings" window to allow easy selection of default file directories
• Tab key now mostly works throughout most of the GUI (needs improvement)
• Main window will no longer disappear when setting a video multipler which results in a window size larger than the current desktop resolution
• Added two new advanced options: one to control GUI window opacity, and one to adjust the statusbar text

bsnes v0.028.01 source Released

While v0.028's release went a lot better than expected, there was one significant problem: it appears that the Linux OpenGL renderer did not work correctly on any of the four ATI graphics card drivers. It seems to be related to partial implementations of GLX v1.3 (you know, the ten year old Xlib interface for OpenGL?)

Rather than continue fighting these drivers, I instead opted to backport the driver to use GLX v1.2 instead. This seems to work on the fglrx, ati and radeon drivers. I don't know much of the radeonhd drivers, but I believe they lack 3D acceleration anyway.

sinamas also came up with an ingenius trick to work around the X Visual problem: that is to say, a GLX rendering context requires a window with the same X Visual as itself. But it's not possible to change the Visual of the existing window that is passed to the GLX driver. sinamas suggested creating this new window as a child window, and embedding that within the rendering window. This worked wonderfully, and eliminates the need for enumerating all available GLX contexts, which is why I needed the GLX 1.3 API in the first place. bsnes now uses the GLX-recommended Visual, which also eliminates a color problem that existed on the fglrx driver when using the default X11 visual.

I also removed the glClear command inside refresh(), as it was redundant and caused flickering on non-buffered visuals. It might even give a slight speed increase on some cards.

Lastly, [vEX] pointed out that I should use the -D flag for the install command in the Makefile. This has been fixed.

I'm not updating the Windows binary to v0.028.01, as absolutely nothing has changed in the Windows port yet. I'll update again when the Debian repository is synced with the new version.

bsnes v0.028 Released

bsnes v0.028 has been released. The major focus of this release was cleaning up the code even more, and greatly enhancing the Linux port to be an equal with the Windows port.

For Linux users, please note that the safest drivers were chosen by default, rather than the most full-featured drivers. The active driver can be changed by editing settings->configuration->advanced->system.(video, audio, input), and then restarting bsnes. You can also edit the drivers by hand, by editing ~/.bsnes/bsnes.cfg

Available Linux drivers are: video ("opengl", "xv", "sdl" (default)), audio ("openal", "oss", "ao" (default)), input ("sdl" (default), "x"). In particular, the SDL video driver and libao audio driver are very poor performers. The SDL video driver lacks hardware accelerated scaling, and runs tremendously slow. The libao audio driver has horrendous, ~150ms+ latency.

OpenGL is the best video driver, but it requires OpenGL graphics libraries to be installed to use. These do not typically come with open-source video drivers. The Xv driver will at least allow hardware accelerated scaling, offering a tremendous speedup, but some ATI drivers have poor (or even missing) X-Video implementations.

OpenAL is the best audio driver, but ALSA works very poorly with it. OSS4 works far better with the OpenAL driver. The OSS driver has the lowest latency (~15-20ms), but requires the most CPU power. It too has problems when using the ALSA emulation layer.

While the SDL input driver is superior to the X driver (and is the default), if your joypad fails to work correctly and prevents you from mapping any keys (highly unlikely), you can always revert to the keyboard-only X driver. The SDL input driver also appears to cause a ~5-8% performance penalty, so if you don't have any joypads, the X driver may be a better choice.

At any rate, I strongly encourage you to try out each driver and choose the ones that work best for you.

• OpenGL (with hardware filter mode support) and SDL video drivers added to Linux port
• OpenAL (with speed regulation disable support) and OSS audio drivers added to Linux port [Nach]
• SDL input driver (with joypad support) added to Linux port
• Emulator pause option added
• Added option to select behavior of bsnes when idle: allow input, ignore input or pause emulator
• Added support to remap common GUI actions to key/joypad presses on the "Input Configuration" screen
• bsnes will now clamp the video output size when it is larger than the screen resolution
• GUI library has been enhanced, and renamed to hiro
• Fullscreen mode now always centers video, rather than approximates
• Fullscreen mode now works correctly on Linux/Openbox
• Extra layer of abstraction in src/ui has been removed, as GUI lib unifies all ports anyway
• Video, audio and input drivers unified into standard library, named ruby
• All custom headers have been merged into a new template library, named nall
• Makefile rewritten, vastly improved. Allows quick toggling of compiled-in drivers
• Makefile: all object files now placed in /src/obj, binary placed in /
• libco greatly enhanced, no longer requires an assembler to build [byuu, blargg, Nach]
• libco SJLJ driver added; bsnes should now build on any Unix-derivative now (Solaris, OS X, PS3, etc) [Nach]
• Fixed register $213e.d4 PPU1 open bus behavior [zones]
• Windows port will not activate screensaver while bsnes is running [Nightcrawler]
• Visual C++ target no longer requires stdint.h
• And lots more -- mostly code refactoring related

Unfortunately, the GUI rewrite took far, far longer than I ever imagined. As a result, no work has gone into the core emulation for this version. But with the GUI rewrite out of the way, that should change in the near future. And thanks to the new UI library, I can now begin work on adding a cross-platform debugger to bsnes, at long last.

• Major source code cleanup (lib/, ui/miu/, ui/vai/)
• Cheat code editor was broken in v0.026, this is now fixed
• Cheat code file format simplified for human readability
• Makefile install target improvements [belegdol]
• libui replaced with miu GUI library
• Custom video / audio / input drivers replaced with vai HW library
• ppc and ppc64 libco targets added [Vas Crabb]
• x86 and x86-64 libco targets now work on OS X [Lucas Newman]

bsnes 0.026 Released

Since the last public release, I've completely rewritten the memory mapping and cartridge loading systems. With this, I've added preliminary support for the Broadcast Satellaview (BS-X), however very few BS-X games will run at this time. I've also switched compilers from Visual C++/8 to MinGW/GCC4, which grants a ~5-10% speedup over the previous release.

• Major source code cleanup
• Completely rewrote memory mapper to support runtime MMCs
• Updated S-DD1 MMC to use new memory mapping interface
• Improved S-DD1 emulation, thanks to information from orwannon
• Added support for SameGame -- load via "Load Special -> Load BS-X Slotted Cart" menu option
• Completely rewrote cartridge loader to support BS-X, BS-X slotted carts and ST carts
• Created custom dialog windows for multicart loading
• Improved generic memory mapper, which eliminates the need for cart.db [Nach]
• Added BS-X slotted cart detection to generic memory mapper [Nach]
• Linux port will now ignore keypresses when window is inactive
• Linux port will use much less CPU power when idle
• Added detailed compilation instructions to Makefile for Linux port
• Added "make install" target and PNG program icon for Linux port
• Switched Windows compiler to MinGW/GCC4
• Windows executable is now packed with UPX to decrease filesize
• Removed .ufo, .gd7 and .078 ROM extensions; added .bs extension
• Added preliminary support for the BS-X base unit, BS-X base cartridge + MMC, and BS-X flash I/O

bsnes 0.025 Released

bsnes is exactly three years old today. I've posted a new version which adds DSP-3 and DSP-4 special chip support. The DSP-3 is used by SD Gundam GX, and the DSP-4 is used by Top Gear 3000. Please note that the DSP-3 is not fully emulated, thusly SD Gundam GX is not fully playable. Also, due to lack of timing emulation with the DSP-4, the Top Gear 3000 track sometimes flickers in split screen mode. However, it is believed that Top Gear 3000 is fully playable.

I should also note that I have started on SuperFX emulation, as some will inevitably see said code in my source releases. What I have now is nothing more than a skeleton implementation, and absolutely nothing using it is playable yet. I am making absolutely no promises that I will ever be able to emulate this chip. It will take at least several months of work, and even then, the speed will probably be too slow to reach 60fps on any system, but ... I'm working on it. While I have no way to run tests on the actual SuperFX hardware, I will do the best I can to emulate the chip accurately. I will be emulating the caching and cycle delays as best I can, but the information I have on this chip is extremely limited, so don't expect miracles.

Lastly, as promised, I have released the special chips I have personally emulated to the public domain. See license.txt for more information if interested. I cannot release the special chips whose code I did not write to the public domain, but all of that is already available under the GPLv2 (from ZSNES) or the SNES9x license.

• Added DSP-3 support, thanks to John Weidman, Kris Bleakley, Lancer, z80 gaiden
• Added DSP-4 support, thanks to Dreamer Nom, John Weidman, Kris Bleakley, Nach, z80 gaiden
• Started on support for SuperFX, no games playable as chip emulation is less than 1% complete
• Unsupported special chips will now display an alert
• Missing stbios.bin file when loading Sufami Turbo cartridges will now display an alert
• Video settings now saved separately for windowed and fullscreen mode
• Advanced option video<.mode>.synchronize can be enabled for vsync, but will cause sound crackling
• Added menu option to toggle FPS counter
• Minor source code cleanup

bsnes 0.024 Released

This is an interim release between some major changes to the video mode support, which may take a long time to complete. It also fixes a bug with CGRAM access timing, re-adds the Sufami Turbo load menu, and adds support for the ST-010 coprocessor, used by F1 Race of Champions.

To load Sufami Turbo cartridges, stbios.bin must be placed inside a folder named bios in the bsnes folder. There is not currently a warning if this file is missing.

• Improved CGRAM access timing restrictions, fixes a bug in WWF Super WrestleMania
• Re-added Sufami Turbo menu to load ST and ST dual cartridges
• Added support for the ST-010 coprocessor, used by F1 Race of Champions II
• Improved libui to automatically adjust control sizes based on platform, vastly improves Windows UI
• Fixed relative paths in config file for Windows port
• bsnes no longer consumes 100% CPU time when idle on Linux port, thanks [vEX]
• Fixed config file object to not rely on undefined C++ language behavior, thanks Nach

bsnes 0.022 Released

Today marks a milestone for bsnes, and possibly for SNES emulation as a whole. With this new release, bsnes' compatibility has now reached 100.0%, with zero game-specific hacks. With every last commercially released game tested by both FitzRoy and tetsuo55 for at least five minutes each, all known bugs have been resolved.

Now, needless to say, I am referring to the emulation of the base SNES unit. As many SNES cartridges contain additional coprocessors on their PCBs, there are still unplayable titles. So how can I claim compatibility of 100%? Because I don't consider special chips inside game cartridges as part of the base SNES hardware. I realize that many people enjoy these games, and I do actively attempt to emulate as many coprocessors as possible (six are supported thus far). However, coprocessors such as the SuperFX and SA-1 continue to pose very significant challenges.

So, after nearly three years of development, I've finally achieved my primary goal. But it wasn't a complete victory ... I've learned a lot over the years. Emulation accuracy is not black and white -- there are heavy costs to pay and forced tradeoffs to achieve it. I no longer believe there is only one absolute path for emulation, as I did in 2004.

So does this mean bsnes is now perfect? Of course not. There are many technical details that are not emulated correctly. This also does mean that there are no bugs, merely that there are no bugs that we are aware of. While absolute verification of 100% compatibility is obvioulsy impossible, even by actually beating every single game from start to finish, this very well should be the first time any SNES emulator could claim zero known bugs with all known games tested. I very much expect this announcement to entice many new users to begin actively searching for bugs, in an effort to discredit my above claim. My response? Go for it! I would very much appreciate any and all discovered bugs to be posted here, so that they can be verified and addressed.

One major thing that needs to be said, is that there consists of one major hack in all SNES emulators, including bsnes: the use of scanline-based PPU renderers. This necessitates global hacks in all emulators to minimize their inaccuracies. I was going to write up a very long post here, going into specifics, but I've decided an article would be a better place for that. I will hopefully be writing up this article in a few days to post here.

In the meantime, one very important issue does need to be addressed. This version fixes a bug in Uniracers 2-player mode, where the game writes to OAM during active display. Like other PPU global hacks, Uniracers required a special consession. But because this hack only affects one game, it can very fairly be seen as cheating. Suffice to say, bsnes does not contain a game-specific hack, and the change made to fix Uniracers affects all games, but I do still very much consider it to be a hack. The fix I have added is quite literally and honestly more accurate than the behavior of bsnes v0.021. Before, writes to OAM and CGRAM during active display went where a programmer would expect, which would cause bugs when ran on real hardware. Uniracers is the only game known to do this, and it is very dangerous to do so. The writes do go through, but not where one would expect. The access address basically changes as the screen is rendered. With a scanline-based PPU, it is not possible to emulate the individual steppings of the PPU, as there is not enough precision. Further, the entire SNES emulation community has virtually no information on how active display OAM and CGRAM writes work. Now, as Uniracers is the only game known to do this, I had the choice of either intentionally remapping the writes to an arbitrary location, or change it to the address Uniracers expects. Neither would be more accurate than the other, as both are completely wrong from a haradware standpoint. So the decision was to either fix Uniracers and deal with some calling it a game-specific hack, or to leave it broken with absolutely no gain to accuracy. Rather than decide for myself, I asked those who have supported me over the past three years for their opinions. The decision was unanimous to fix Uniracers. You can read the discussion, along with a more technical explanation of the issue, here. I will be addressing this topic in much greater detail in the article I will be writing up shortly.

• Fixed buffer overflow that was manifesting as corrupted tiles in Lemmings 2
• OAM and CGRAM addresses are now invalidated during active display, however the algorithms for how this address invalidation occurs is currently still unknown, so reads/writes are mapped to static addresses for now
• Re-added cheat code editor.
• Windows only: keypresses when main emulation window is not active are ignored once again

bsnes 0.21 (experimental) Released

This is a maintainence release. I am mostly releasing this for the sake of the recently released Der Langrisser translation.

• Windows port can once again map joypads through the Input Configuration panel
• Using enter or spacebar to assign a key should no longer instantly map those keys
• F11 now toggles fullscreen mode
• Esc now toggles menu on and off (use F11+Esc combined to hide UI completely)
• Fixed a bug in King of Dragons (J, U, E), KOFF was not cleared during S-DSP power(), thanks to FitzRoy for the report, and blargg for assistance fixing the bug
• Fixed serious crashing error with File->Load on Linux/amd64 port
• Hopefully fixed min/max undefined error on GCC 4.2.0, but I am unable to test to verify
• Fixed many cast const char* to char* warnings for GCC 4.2.0, but some probably remain, as again, I am unable to test as I lack GCC 4.2.0
• Set XV_AUTO_COLORKEY to 1 for Video/Xv renderer. Should fix some video drivers where there was no output, especially after running mplayer, etc. Thanks to sinimas for the fix
• Added clear_video() to Video/Xv renderer. Green edges at the bottom and right sides of the video output are now gone, and unloading a ROM will clear video

I have finally figured out how to poll the keyboard status in real-time through Xorg: the XQueryKeymap function. I will be rewriting the Linux key capture system to use this, instead of capturing window key up / down messages through GTK+. This will finally allow me to completely abstract the UI from the hardware video, audio and input interfaces: a necessary step toward Linux joypad support.

bsnes 0.20 (experimental) Released *source updated*

UPDATE: The source package has been updated to fix some small issues for 64-bit systems.

First, it appears bsnes was crashing on Linux/amd64 platforms when selecting 'File->Load Cartridge'. The cause of this error was quite fun to track down. Luckily, I came across the fix in a kino changelog. It appears that gtk_file_chooser_dialog_new() is a vararg function. The very last parameter passed is pointer to a string. However, if you don't need this parameter (and I don't), you can pass it a null pointer. Well, null is defined as 0 in c++ (and (void*)0 in c). This is no problem on 32-bit architectures as an integer and pointer are the same length. But on Linux/amd64, an int is 32-bits, whereas a pointer is 64-bits. So, I was pushing half of the pointer, but the upper half was basically not set. So whenever the stack happened to contain a non-zero upper half, GTK+ would think the pointer was valid, and attempt to read from it. Quite a serious issue, I can see many people running into this problem. It's non-obvious, as non-vararg functions will promote int(0) to 64-bits automatically. The solution is to cast vararg null pointers explicitly. In my case, I had to replace 0 with (const gchar*)0.

Next, during the rewrite, I never added back command-line loading. Oops. This is now fixed.

Lastly, I came up with a proper fix for casting between integers and pointers: uintptr_t. This is a variable declared in stdint.h that states it is safe to cast a pointer to an integer, and then that integer back to a pointer. This is definitely the proper way to implement my window message passing system, and as such I have rewritten the relevent parts of libui and bsnes/lui to use uintptr_t. This should fix all compilation errors on Linux/amd64.

Five months and 43 WIP releases in the making, today I am releasing bsnes v0.020. I'd really like to express my thanks to blargg, for he has written a new S-DSP emulator that is an impressive 32 times more precise than all existing S-DSP emulators. It is now bus-accurate, and should produce bit-perfect sound output to that of a real SNES, excepting very minor, very extreme edge cases. Not only did he do this, he went out of his way to develop a special version exclusively for bsnes to ease licensing concerns and take advantage of bsnes' unique features, notably cothreads. I can't thank him enough. Unfortunately, bsnes has taken a ~10% speed hit over v0.019 by using this new S-DSP emulator, but I must stress the speed hit is entirely due to the way bsnes is implemented. blargg's standalone S-DSP emulator is very, very fast. Anyone is free to take a look at his S-DSP emulator, as he has released it as open source under the LGPL, by visiting his homepage, here.

Unfortunately, the new cross-platform UI is not entirely finished. Some sacrifices had to be made to support libui. Specifically, the following features are missing from v0.019, but will hopefully be added back in future releases:
• Fullscreen support
• Input Configuration panel cannot capture joypad input. Joypad support is still present, but it must be mapped manually through the Advanced panel or through editing bsnes.cfg by hand
• The Cheat Code Editor is missing, but cht files can still be used from bsnes v0.019, and created by hand
• Sufami Turbo support is not accessible from the UI
• The UI on Windows is slightly less polished due to compromises to allow the UI to be readable on Linux.

I am sorry for the rough edges listed above, but I wanted to get a new release out, as it has been over five months since the last release, and I really want the world to be able to experience blargg's new S-DSP emulator.

• Added blargg's new S-DSP emulator, runs at 1.024mhz. Many thanks to blargg for this, as this puts all portions of SNES emulation except for the S-PPU at bus-accuracy
• blargg's S-DSP core fixes bugs in both Koushien 2 (J) and Toy Story (U)
• Corrected all S-SMP cycle timings to be hardware accurate. Thanks to blargg for creating an amazing test ROM that tested every possible opcode
• Corrected S-CPU wai instruction timing, fixes Mortal Kombat II
• Reverted HDMA sync emulation once more to fix Breath of Fire II (G) and Secret of Mana (U)
• Completely rewrote user interface to use libui, which is a wrapper that allows the same code to produce the same UI on both Windows (through the Win32 API) and Linux (through the GTK+ API)
• Corrected $2100.d7 OAM reset behavior, thanks to research from anomie
• Massively revamped the Linux port, should compile with no warnings or errors now
• Added 64-bit support to libco, tested on FreeBSD/amd64, should work on Linux as well
• Revamped makefile with suggestions from Nach
• Improved Linux Xv renderer to use the far more common YUY2 format, which should work on most Xorg drivers, allowing hardware accelerated video scaling
• Completely rewrote config file system. bsnes.cfg is now saved to user's profile folder on both Windows and Linux, allowing multi-user support
• A lot more work has been done behind the scenes, including massive code cleanups and portability improvements

SNESGT 0.218 Released

A new version of this SNES emulator has been posted, no list of changes is available in english though. Here's a crude translation by google langauge tools:

- envx of sound DSP, correcting the behavior of the outx register
-- 0.217 So [enbagu] correction of those which are done
- Correcting mounting the sprite priority rotation
-- Correction of the bug which damage indication of FF mystic QUEST turns to rear
- Correcting the address mirroring of the SPC port

It is there is no excessive big renewal point but, bug entered to the relation of sound with 0.217, because sound has become strange with wide-ranging title, made to release new version.

bsnes 0.19 (experimental) Released

I'm releasing bsnes v0.019 today. This version contains Bandai Sufami Turbo support, new IRQ emulation code, and some various bugfixes.

Unfortunately, this release is not entirely cause for celebration. Due to fatal errors in Microsoft's "enterprise class" c++ compiler package, I am no longer able to compile bsnes with profile guided optimizations. I have tested v0.018 with and without these optimizations, and the difference is a 40% speedup when PGO is used, even more significant than I had previously believed. However, bsnes has now become too complex for Visual C++ to handle. Unfortunately, there is nothing I can do about this, except wait for Microsoft to fix their compiler.

(Warning: this paragraph contains personal opinions, skip it if you can't handle that) As if this wasn't enough, I'm now doing my best to wean my dependence from Microsoft's line of operating systems, as I'm particularly concerned about the black box nature of Vista and its' DRM control mechanisms. This isn't a road I wish to begin traveling down, and thusly have no interest in upgrading to future versions of Windows. Therefore, as of late, I've been writing a UI wrapper that will allow me to code applications that are truly platform independent. The biggest goal for this library is to design a GUI for bsnes that runs virtually identically on both Windows and Linux/BSD. This is mostly complete, however there were many tricks I used in bsnes using the win32 API that I simply cannot do with GTK+ on Linux/BSD, such as the memory editor window subclassing. I will be porting bsnes to use this new UI wrapper, and in turn this will lessen the attractiveness / functionality of the bsnes UI to a certain degree.

Perhaps the most devastating news is that I am still contemplating the idea of designing a dot-based PPU renderer for bsnes. As if the loss of PGO wasn't bad enough, this will likely eat away an unimaginable level of performance as well. I can only estimate the speed loss being between 100-500%. Yes, it will be that bad. And despite weeks of planning, I cannot think of a way to allow a scanline-based and dot-based renderer to coexist as selectable options, given their massive differences in implementation.

And let's not even joke about SA-1 or SuperFX support ... those processors are each four to eight times more powerful than the SNES' main CPU.

All of these speed losses will basically make bsnes mostly irrelevant as an alternative to ZSNES, SNES9x et al. Although I believe I really came close to a viable alternative with v0.018, I know that I cannot both create a mainstream emulator, as well as keep with my original goal to emulate the SNES as accurately as possible.

The past few months have been very tough for me; trying to decide which of the above two goals to pursue. I've still not absolutely made up my mind. But for now, I've been sitting on a mostly untouched version of bsnes for the last few months, and have decided to release it to the public, profile guided optimizations be damned.

I'm once again asking for help, if anyone can figure out why bsnes won't compile with PGO support, please let me know. I'd very much like to get one last PGO build of bsnes released before starting on a dot-based PPU renderer. But given the usual response I get from these requests for help, I'd suggest no one getting their hopes up that bsnes will ever be as fast as it once was again.

The new version can be downloaded at the usual place. I'm leaving v0.018 up, as it may very well be the last stable, fast version of bsnes ever released.

ZSNES 1.50 Released

All Ports:

For this release we spent much time rewriting, porting, improving many internal subsystems. ZSNES is a program with over 200,000 lines of source code and in this release, over 25% of that has been modified. Also around 15% of assembly has been ported to C. The upcoming list while large can't fully describe the amount of work and the amount of improvements made. Make sure to see the readme to find out how to use all the new features.
Subsystem Additions/Updates/Rewrites/Fixes/Improvements

* Ryan C. Gordon's ManyMouse support added. [Nach, pagefault]
This allows the systems compatible with ManyMouse ((Windows XP, Linux via evdev if read permission set, Mac OS X) to handle each mouse plugged into the system separately. So now games with two mice using devices can be played with 2 player (or 1 player controlling both) on a single PC.
Left Handed Mouse Support. [Nach, Deathlike, Jonas Quinn]
So lefties can have the buttons for a particular mouse swapped if they so desire.
* Rewrote directory handling system. [Nach, Jonas Quinn, grinvader, Deathlike]
The old system dubbed "ZFile" only kept track of files in a limited manner allowing for many many bugs. The new system dubbed "ZPath" now tracks files and paths in a clean systematic manner to eliminate all file/path related bugs that have made previous versions annoying. All file handling code is now done in C and has many functions to make it easier for anyone else to jump right into this bit of development. This also allows for many new features to be written, and we wrote quite a few. A debug system has also been added making it easy to track file issues regardless of the operation system in question.
* ZMV Rewritten - Movie Support. [Nach, grinvader, ipher]
Added support for subtitles while playing a ZMV. [Nach]
Can now load movies via command line parameter. [Nach]
Added parameter to close ZSNES when movie is closed. [Nach]
Our movie subsystem - ZMV has been completely rewritten from the ground up. Now features such as rerecording (via states and rewind), appending, mouse recording, Super Scope recording (buggy), chapters, start types, frame count, input compression, among other things is now all supported. Note ZSNES can still load old ZMVs, however it should be noted that ZMVs are somewhat version reliant and may desync on a version it was not recorded with. Also most of the new features will not work when using an old ZMV.
* Can now dump ZMVs to AVI and WAV. [Nach, Bisqwit]
For years users have requested being able to convert a ZMV to something else, it is now possible.
* Added IPS multipatch support. Goes from IPS, IP0, IP1, IP2, ..., IP9. [Nach]
So you can have IPS autopatching apply more than one to a game loaded.
IPS files now loaded from save directory then ROM directory. [Nach]
Making it easier for a user to auto patch.
Fixed silly mistake with size adjustment of IPS patches. [Nach]
So now the very rare broken IPS should work.
* Rewind and ZST code fully merged rewind should now work where save states do (Fixes rewinding in Super Bomberman games). [grinvader, Nach]
Can now use 100 save states instead of 10. [Deathlike, Nach, Jonas Quinn]
SRAM is now stored in save states and can be optionally loaded from them. [grinvader, Nach]
Can now select how many rewind states you want. [grinvader, Nach, ipher]
Can now select how much time is in between rewinds. [grinvader, Nach, ipher]
Our state saving subsystem has been completely rewritten (although another rewrite is planned) to fix many bugs that used to be present. With the ZST and rewind code merged, it also means no more issues where one works but not the other. This is also now all done in C making it easier to deal with, as well as allowing many new features as listed above.
* Parsegen invented (thanks grinvader, gladius). [Nach]
Binary and text config files merged into one and heavily updated. [Nach, grinvader, Deathlike]
We invented a new programming language (PSR), and a compiler for it (parsegen), which allows one to keep track of variables in a simple manner for both developers and end users. Developers can just declare a particular variable to be tracked and forget about it, letting the system manage everything else, making it easy to add as many configuration options as one likes. For the end user, the config file is all in text, making it easy to modify any feature they like or features for advanced users not changeable from within the GUI. It also provides a level of future compatibility so users should normally not have to delete config files between versions. It also allows partial config files, so users can delete certain settings and have them restored to their defaults. All this is possible while maintaining a high level of flexibility.
* Netplay, Modem, IPX code removed. [grinvader, Nach. ipher]
As much as we hated to, we had to remove all computer to computer playing options in order to fix up the other subsystems since the code was spread throughout ZSNES. We hope to in future versions to reimplement it and also provide new features.
* Created new macros and greatly eased GUI development and cut down on size of GUI code. [ipher]
Cleaned up GUI and reorganized it. [ipher, Nach, grinvader, Deathlike, Jonas Quinn]
Added tab support to the GUI and made good use of it. [grinvader]
Rewrote the load game menu, it can now handle thousands upon thousands of ROMs at a time. [Nach, grinvader]
Added a custom font system. [ipher, Deathlike]
Nach input boxes (video, path) now have a normal blink rate. [Nach]
Now using our custom GUI should be easier and more straight forward. Almost everywhere you look you should see a cleaner design and new features, and less bugs. See below for more specifics.
* New unified ZSNES loader which is also less buggy. [Nach, grinvader, Deathlike, Jonas Quinn]
Now command line options are handled in a more efficient manner, as well as making it much easier for us to add more.
* Committed the ZSNES development toolkit. [Nach, grinvader]
Code is now always in executable sections, fixes NX and many other issues. [Nach]
Added utility to auto detect best -march option to compile with, SDL port uses it automatically. [Nach, grinvader]
For various developers, we now added many utilities to make working on ZSNES much easier. Some of these utilities should be built into the assembler but aren't. These new utilities have also allowed us to easily track down several critical bugs and fix them effortlessly. We also have a utility now to aid the person compiling to get the best optimization out of their build perhaps now allowing them to use HQ4x or other filters that weren't possible before.
* Updated build setups. [grinvader, Nach]
Added file dependency utility. [Nach]
All the build setups have been updated to make it easier and more flexible for one to compile ZSNES and encounter less bugs along the way. File dependencies can now also be calculated automatically (most notably for SDL), so one updating ZSNES doesn't run into weird issues with only half of a fix being compiled.
* Ported much assembly to C. [grinvader, Deathlike, Nach, Jonas Quinn, theoddone33, pagefault, byuu]
Removed dead code. [grinvader, Nach, pagefault, Jonas Quinn, Deathlike]
Lastly on our big rewrite, a lot of old junk went, and many complex are annoying features are now in C meaning if you know C, now is a good time to start helping out ZSNES development.

bsnes WIP Report

A new bsnes work in progress report has been posted today.

I rewrote a lot of the cartridge file processing code to support the Bandai Sufami Turbo. All thirteen games are playable, and all are dualable in any combination. There are a few technical limitations such as SRAM always mapping as 128kbit in all games and cheat files only loading from the first cartridge (ROM cheats being unreliable when you switch which slot a given game is plugged into anyway), however since all games are fully playable, and this technically has little to do with the SNES, I am very satisfied with the results. The technical limitations are mostly related to the abstraction of the bus controlling PCB-based memory mapping (the MMC obviously exists in the cartridge, whereas the memory mapper is the most logical location to decode addresses in an emulator), thusly expecting single linear blocks for ROM and RAM, and the Sufami Turbo requiring two separate ROMs and SRAM regions. While it's possible to get around this, I've decided the additional work and overcomplication of one of the most vital parts of emulation is not worth the effort for only thirteen games. Hopefully everyone will agree that my Sufami Turbo implementation is more than sufficient.

I also fixed a tiny glitch with IRQs affecting Final Fantasy: Mystic Quest (E) (yes, that's right, I'm calling the European version Final Fantasy, take that Square), which may or may not have affected the last public release. I'm currently working on an IRQ fix that will correct both R-Type III and Robocop at the same time, but every fix I come up with breaks one of my test ROMs, fun.

Lastly, a fix for Michael Jordan: Chaos in the Windy City, single writes to BGnVOFS registers appear to act differently than single writes to BGnHOFS registers. Check the ZSNES forum if you want to read my long-winded technical explanation of this. The maps now ... do whatever it is they do ... correctly.

bsnes 0.018 Released

I began working on bsnes on October 14th, 2004. I am releasing bsnes v0.018 today to celebrate bsnes' two year anniversary. Please note that this release incurs a ~15% speed reduction since v0.017, due to IRQ and S-SMP timing improvements.

• Fixed many critical errors in IRQ timing, should be *very* close to real hardware now
• Corrected major CPU timing bug involving CPU I/O condition 4
• Corrected bug with generic HiROM / LoROM memory maps
• Corrected bug involving HDMA indirect channel termination [anomie]
• OAM address reset now occurs when screen display is enabled, per recent research
• Readded full DMA, HDMA and HDMA init bus sync timing
• Added preliminary emulation of S-SMP $00f0 TEST register (6 of 8 bits are supported)
• Readded emulation of known timing differences between CPU revisions 1 and 2
• Config file can now control scanline-based PPU render position. This will only be needed until a proper dot-based PPU renderer is added
• Removed core debugging hooks so that debugging console can remain in public releases, it now functions as a tracer and memory editor
• Config file paths once again work correctly even if missing trailing backslash
• Video configuration simplified, sorry in advance to those who enjoyed the profile mode used before
• Added new configuration screen to control some emulation settings
• Replaced bsnes program icon with a much nicer one [FitzRoy]
• Optimized memory speed detection algorithm
• Preliminary UPS soft-patching support (do not use this yet!)
• Decreased memory usage and optimized generic libraries used by bsnes (/src/lib)
• Now caching OAM by one line, somewhat similar to a real SNES. Fixes Winter Gold, but causes line rendering error in Mega lo Mania
• Lots more, as usual

The following games have been fixed since v0.017 by the above bugfixes:
• Battle Blaze (J, U)
• Circuit USA (J)
• F1 Grand Prix (J)
• Funaki Masakatsu no Hybrid Wrestler - Tougi Denshou (J)
• Jumbo Ozaki no Hole in One (J)
• Mahjongg Taikai II (J)
• RPG Tsukuru - Super Dante (J)
• Robocop Versus The Terminator (U, E)
• Sink or Swim (U, E)
• Street Racer (J)
• Touge Densetsu Saisoku Battle (J)
• Winter Olympics (U, E)
