Fix memory block alignment in RomBanner for 4-byte wchar_t, #3354040

From rogerman:

The RomBanner struct requires UTF-16 strings for the six different ROM titles.
Currently, we use wchar_t buffers to define the memory blocks where the title
strings are supposed to go. Using wchar_t is fine for compilers that assume a
2-byte wchar_t. But compilers that use a 4-byte wchar_t will misalign
the memory blocks.

I've submitted a new patch that changes all the wchar_t in RomBanner titles
to u16 for all ports. It took me a while to research the dependencies on
titles, and to make sure I didn't accidentally break something in the
Windows port.

As for the wcscpy() deal in the RomBanner constructor, it's an arbitrary
default init value that we don't actually use in practice, so I removed it.
If a particular port wants to know what to display for the titles when a
ROM isn't loaded, there are plenty of ways to figure this out. Or they can
just check the titles for an empty string, which the constructor inits the
titles to before the wcscpy() call.

For CHEATS::save(), I removed the dependency on using titles. The ROM name
we write to file is also an arbitrary value which we don't actually
reference in practice. I changed it to use gameInfo.ROMname, since we're
already using gameInfo.ROMserial.

D PSP Emulator SVN r300

via http://www.emucr.com/2011/07/d-psp-emulator-svn-r300.html

D PSP Emulator SVN r300 is released. D PSP Emulator is a PlayStation Portable (PSP) emulator for PC made in D programming language. At the moment can run some simple homebrew. It doesn't load any comercial game at this stage.

D PSP Emulator SVN Changelog:
r290
- Fixed sceKernelWaitThreadEnd(CB) + Unittesting
- Fixed??! sceCtrlReadBufferPositive and sceCtrlReadLatch + Unittesting
r291
- Stop all the emulator when an error rises. @TODO CHECK! It loses the exception
launched?
- Minor changes and refactorings
- Changed the way sceCtrl waits for a frame. Still not accurate.
- Some changes and fixes on IoFileMgr_FilesAsync
- Implemented some more NIDs
- More changes and fixes on ThreadMan
- Disabled/Enabled all threads on sceKernelCpuSuspendIntr/sceKernelCpuResumeIntr
still have to check if it works as expected.
- Fixed sceKernelLibcClock
- Fixed PspLibDoc singleton (not used __gshared; was Thread Local Storage)
- Added and fixed tests for module loading
- More tests
r292
- Implemented simple voices on sasCore (still has some issues)
- Implemented sceAudio.sceAudioSRCOutputBlocking
- Minor changes and refactorings
r293
- Updated to D v2.054
- Fixed some issues and cleanups
- SwitchGen is now faster (probably MUCH faster) using AA instead of plain
arrays because of being able to use AA on CTFE. Because of that, there is no
need for "cached_switch_all.dcode" file anymore and it has been deleted. By
faster I mean on compiling times. On runtime it should be as fast as always.
- Added a link to the online compatibility table (not enabled yet)
- Added a new option to force to check updates: --check_updates
- Fixed ApplicationPaths
- Fixed SvnVersion.getLastOnlineVersion on v2.054 because of the non-greedy fix.

DS2x86 version 0.20 released!

Pate has updated his Dos Emulator for the Nintendo DS, heres the news:

Sorry it took me over a month to get a new version released. However, this version now has two noteworthy improvements, namely FPU support and the fact that this version is now built with version 0.13beta of the SDK. This version of the SDK has already been released at the end of last year, but I only recently noticed that I still used the even older 0.12beta version to build DS2x86. This might have caused at least some of the audio problems, as the audio features were somewhat improved in SDK v0.13beta. I also decided to jump the version number to 0.20 with this version, to show that it has some major internal changes.

The biggest enhancement is the addition of FPU support. For now this only works in 32-bit protected mode (meaning those DOS4GW games), as those are the games that mostly expect the existence of an FPU. My two test games, X-COM UFO and Destruction Derby, now seem to run the FPU parts fine. The problems I mentioned in the previous blog post were actually both caused by the FPU opcodes, though in some rather interesting ways. It took me almost three days to track down and fix the problems. There is still a rather serious problem in the texture mapping in Destruction Derby, but I am not sure if that has anything to do with the FPU opcodes. In any case, Destruction Derby runs much too slow to be properly playable, so fixing the texture mapping is not a high priority. Fixing it might fix some other games as well, so I do plan to look into it at some point.


Anyways, the FPU problem in Destruction Derby was in the FCOMP (compare) opcode. When I first tested that opcode it seemed to return a correct result, so I spent a lot of time looking elsewhere for the problem. In the end it turned out that I had a small typo in the opcode handler, I had written "sll t4, t3" when I meant "sll t4, t3, 1", and the assembler had interpreted it as "sllv t4, t4, t3". In this case the assembler tried to be a bit too smart, when it replaced the sll opcode (which can only have an immediate shift value) with the sllv opcode (shift by a register value). Since I had forgotten to type the immediate value, it would have been nicer if the assembler had given an error instead. That problem meant that the comparison result was mostly random, it sometimes returned the correct result and sometimes not, somewhat depending on the lowest 5 bits in the registers I wanted to shift left by one bit before the comparison.

A more interesting problem was the one that affected X-COM UFO. It behaved very erratically, dropping to a debugger with an unsupported opcode at random locations, where the opcode should have been supported. That pointed to the interrupt routine failing to execute properly and dropping back to where the interrupt should have happened. It took me a while to notice that when it dropped into the debugger, the Virtual 86 mode flag in the flags registers was set! I had not coded support for interrupts in virtual 86 mode yet, so that was the reason for the weird unsupported opcodes. However, I was pretty sure that the game does not set this flag on purpose, so I added a check into DS2x86 to drop to the debugger immediately after this bit gets set in the CPU flags. After a few test runs, the results were quite interesting. Once the bit did not get set, but DS2x86 dropped into the debugger anyways. In other runs, twice the opcode was fsin, and once fcos, two of my new FPU opcodes.

The interesting part was that I did not touch the CPU flags in the fsin and fcos opcode handlers at all! I did store the register that contained the flags into stack, along with various other registers that calling the GCC math library sin() and cos() functions will globber, and then restored the registers after the call. I could not immediately see anything wrong with my code, so just for fun I copied the flags before the GCC library call to the EAX emulated register and the same flags after restoring them from stack to ECX emulated register, and then added a forced drop to the debugger after the call. And, much to my surprise, the value restored from the stack was completely different to the value I pushed to the stack!

I looked into the dump file for what happens in the GCC library sin() and cos() functions, and noticed that indeed, they destroy the two topmost words of the caller's stack!. I have a very hard time believing this behaviour is by design, this might actually be a bug in the GCC compiler itself. Here below is the dump from the start of the math library sin() function. The input is a 64-bit double value, in 32-bit registers a0 (low word) and a1 (high word).

80251014: afa5025c sw a1,604(sp) // Store the high word of input to sp+604

You can see that the routine first reserves 600 (0x258) bytes of stack space for local variables, but then stores the input value to offsets 600 and 604 from the start of the reserved space! This effectively destroys the two last words that the caller had pushed into the stack, which in DS2x86's case were the emulated CPU flags and a stack size mask register. So, after returning from fsin or fcos routines, the flags were randomly set, and also the stack-relative addressing might have addressed the wrong memory area.

This problem was easy to overcome by leaving two extra words to the top of the stack when calling these functions, but if you are writing software for DSTwo yourself, beware this problem! I spent some time googling whether this was a known problem and if a fix is available, but did not immediately find anything. Let me know if you know the correct place to look for this information!

I also made some other fixes, based on the debug logs you have sent. Still another change is that I changed the Makefile to compile the C modules with -no-long-calls option, which makes the code smaller and faster. I don't know why the SDK defaults to long-calls, as they are only needed if the code does not fit into a single 128MB block, and the DSTwo only has 32MB of RAM! Anyways, let me know if you run into any new problems with this version, and feel free to test the games that used to report unsupported FPU opcodes! Thanks again for your interest in DSx86 and DS2x86!

Windos final

Heres another multi emulator released for the PS3:

Samson posted this

now slimmed down to 100mb
added xmb menu music
dpad mapped to arrow keys , start=enter, select=backspace

new programs and games all launchable from the start menu..

added games:-
another world
hitchhikers guide to the galaxy
ghouls and ghosts
metal gear
shinobi
and lots more also a few wolf 3d mods

emulators:-
colecovision.. some launching problems , run as dos session
Fmsx (msx) (windows and dos versions)
x5200 (atari)
pc64 (com64)



i've set up dos based emus to launch from a run.bat so end user can edit and add game to be run, if you have problems try running from explorer, run, run as dos session.

also added, ps3hax theme wallpaper by Kajika, usb support(no hot plugging) a fake cd rom(folder) to copy file into (ps3 file manager or ftp) a windows based hex editor, so i think i am about done with it most 3d game lag.. but all 2d and simple 3d work. running slow-Pentium fixed@4000 BUT you can bump the cycles up as much as you want, but sound will suffer.

also i still cant get win32s to work on ps3 , works fine on pc .. go figure.

PS3roar

News via http://blackbird.usask.ca/forum/viewtopic.php?id=41

This is the official thread of PS3roar at Homebrew Café, I'll try to keep this thread upto date as much as possible as development completes.

What is PS3roar? Good question!

PS3roar is a port of xroar for X windows, as well as; the Nintendo DS, GPX32, PSP and AMIGA OS4. PS3roar is a Dragon 32 and 64 Computer emulator that runs on a wide variety of platforms, now including the PS3. Due to hardware similarities, PS3roar also emulates the Tandy Colour Computer (CoCo) models 1 & 2.

The PS3 port and modifications completed by CrashSerious (me). The PS3 port uses PSL1GHTv2, a free and Open Source SDK for the PS3.

PS3roar is a Dragon/Tandy Coco emulator, is a port of xRoar by Ciaran Anscomb.

xRoar is Copyright (C) 2003-2010 Ciaran Anscomb
Below is an image as it currently is in development:

The currently working options in the emulator are:

- 6809 emulation
- Video display (at original pixel size) on the display w/ background
- Keyboard emulation with PSL1GHT_SDL that has a keyboard Driver (https://github.com/CrashSerious/SDL_PSL1GHT)

Unofficial r2649 beta20 - Jul. 24, 2011
can adjust decline number (2-17): The higher the number, the faster but some games are unstable while anoter some games work only in the lower number (ex. 2-4) but slower.
adjust for PAL monitor mode when libogc detects VI_PAL mode (but I cannot verify this forever)
fix threading
some minor fixes and changes
