Game Boy Advance Test Suite

mgba: endrift has posted on his forums about a gba test suite

In the interest of furthering the state of Game Boy Advance emulation, I've been writing a test suite that tests various aspects of hardware. At the moment, it only tests timing operations, but way more will be coming in the future. Source code is available on github
Timing tests
Each test contains 20 (or 10 if only an ARM version is supported) configurations:
ROM 4/2 waitstates, no prefetch
ROM 4/2 waitstates, prefetch
ROM 3/2 waitstates, no prefetch
ROM 3/2 waitstates, prefetch
ROM 4/1 waitstates, no prefetch
ROM 4/1 waitstates, prefetch
ROM 3/1 waitstates, no prefetch
ROM 3/1 waitstates, prefetch
The current version contains 1260 tests total.

mGBA (master): 1098 passes
NO$GBA 2.8a: 759 passes
VBA-M 2.0.0 beta 1: 680 passes

VisualBoyAdvance-M GTK+ svn r1001

News via AEP

A new SVN build of the Nintendo GBA and GB/GBC emulator VisualBoyAdvance-M has been released.


Removes NO_OAL from the project file to restore compiling to its full form. Specifying such an option should be done per user and should not be set by default.

patch from billiard to attempt a fix for the broken DI8 enumeration.

Directinput fixed.





and this ends a bunch of updates including msvc10 project files, billiards directinput patches, and changing of the project name to visualboyadvance-m in the project files.
nasm seems to bitch when there are spaces in the folder path, and i havenīt yet worked out how to fix this in nasm.target so if anyone has an idea yeah
thanks for the patchs billiard


enable SSE optimisations in VCProj, intrinsics update nasm and revert shuffles changes to gb_apu_state.cpp.
i prefer warnings during compilation rather then a lack of function in the emulator, we can look at correcting the warnings in a less broken manner later.

by popular demand, the layers menu is back.

filters was named wrong for some reason O.o


killed off 22 warnings by removing a command line override for zc:forscope.

applied patches by jlaukkanen Import Pro Action Replay Snapshots Compilation error when no_xaudio2 Focus Lost in cheat dialogue MFC

more patches, save type detection now only available when a rom is loaded.

another patch, this time for GSV snapshots.

gdbconnection patch - fixes remote debugging

gdbconnect patch, fixes remote debug

stupid log told me it wasnīt patched but it was

streamlined vcc directories some.

applied gtk_rtc.patch by unmacaque

LZMA2 support for file_extractor by Kode54


linux build fix, pushed to svn.

debian build fix

lets try this one more time

applied kode54īs sdl/gtk joypad patch

missing ; after break on line 263

SVN: Applied proper properties to all files, mainly to get native end of lines.

GTK: Fix the joypad config dialog using 100% CPU

GTK: Convert the remaining parts of the UI from Glade to GtkBuilder. Thanks to Rafał Mużyło for the patch.

GTK: Rename the main GtkBuilder file for consistency

GTK: Donīt reset the renderer when entering the display config dialog

CMAKE: Allow building without SFML

CMAKE: Use built in support for ASM compilers. Bump required version to 2.6.0

DEBIAN: Build one package for SDL, and one package for GTK+. Thanks to fernandotcl for the patch.

GTK: Added GBA cheats support. Thanks to unmacaque for the patch.

GTK: Cleanup includes. Donīt instanciate global objects.

GTK: Turned the last menu based settings into a dialog

SVN: Set more properties

GTK: Remove the StringTokenizer class and move the functionality to tools.cpp

GTK: Mark more strings as translatable

TI83 Emulator 22/01/09 released - TI83 Emulator for GBA

Dwedit has popped up with a new version of his TI83 Emulator for GBA, heres the release notes:

Here is a Multiboot version of the TI83 emulator.
If you trim the TI83 rom, the file size of the rom is about 215900 bytes large.
You can also attach a .83G file up to about 14000 bytes large, and use L+R to send it.

If the GBAMP firmware refuses to boot the file, use the PocketNES firmware instead.

Edit: Using Pocketnes firmware to run the emulator may be buggy. It crashed when I tried sending a game to the emulator. Using GBAMP's firmware didn't boot the emulator at all for me.

NGPAdvance V0.2 - Neogeo Pocket Emulator for GBA

Flubba has released a new Neogeo Pocket Emulator for GBA:

New version of NGPAdvance, a lot of games should be a bit more playable thanks to speedhacks. I also added support for a lot of internal hardware (RTC/Alarm, Power button, DA/DA IRQ) so that you can use the real bios. Still no flash emulation as I can't really see how to implement it on the GBA... Also uploaded a tech doc for the NGPC.

*Added speedhacks for a lot of games.
*Added emulation of batteries & sub battery.
*Added RTC alarm.
*Added power button (SELECT).
*Added D button (R) (check Doko Demo Mahjong).
*Fixed a couple of cpu bugs affecting Metal Slug 1 and a couple of other games.

no$gba 2.6a Released

No$gba Newest-Gaming-Version Downloads
Donate $2.50 (via paypal) and Download newest no$gba version (support the no$gba project)
[hint] I am currently having technical problems to create a new donation button for v2.6a, so, if you've bookmarked the v2.6 download address, then you can re-use it for v2.6a, too. Anyways, would be even better if you would threw in a new donation :-) Also because the address is unchanged, some browsers may have memorized the old v2.6 files, and may keep giving you that old files - in case of problems: bookmark the download address, and try again later. To avoid another problem: Be sure that you don't forget to click the "Return to Merchant" button at the paypal page when you've sent the money.

Why that donation stuff...?
I've had some money saved up when starting to make no$gba in summer 2001, during last some years the money became less and less, so, without some new money, I won't be able to continue to work on no$gba much longer. Now, if less than one of a hundred people would click the donations button - that would probably solve no$gba's monetary problems.

Snezziboy v0.25 Released

This is what seems to be the last update on this wonderfull Snes emulator for the GBA hardware, Thank you Bubble2k!

The release notes spells out all changes in detail. But in summary, this is what I've done:

1. Fixed some DMA bugs - Final Fantasy Mystic Quest seems playable

2. Fixed the subtraction bug - so that Zombies ate my Neighbors now work

3. Partially fixed and restored the SNES additive transparencies capability

4. Fixed Mode 7 wraparound. - Super Metroid intro: Samus' ship does not repeat; Secret of Mana: world map during cannon jump wraps around at the edges.

5. Fixed bug in the emulation of some other instructions and PPU registers.

6. Implemented partial HDMA (currently only updates BG scrolling position) - DKC3 works, FF3 backgrounds scroll correctly but text still invisible.

7. Made slight/major optimizations to the code based on Gladius suggestion. Most games should see some slight, but notable speed increase.

As usual, I hope I do not break any existing working games...

EDIT: This version's mainly some bug fixes and the partial implementation of HDMA. I wouldn't consider it a major success in implementation, but rather a proof of concept. There aren't too many fixes to the garbled graphics for this version unfortunately. But I would like to move on to the DS for v0.26 to fix that issue up. Many things are much easier on the DS.

Snezziboy v0.23 Released

A great update by Bubble 2k

These are some of the changes this round, if anyone is at all interested.

- Fixed a critical bug with the register reads and writes (might be slower)
- Improved cycle counting (again) for block move and DMA operations.
- Added feature to handle mid-frame change of background offsets.
(Able to see water in Super Mario World,
Able to see scrolling clouds in Super Mario All Stars: Super Mario Bros,
Able to see fixed status panel in Super Mario All Stars: Super Mario Bros 3,
Able to see scrolling name entry in Zelda: A Link to the Past)
- Fixed reading register $4212 to indicate auto-joypad read status.
- Fixed writing register $4016 to reset only when the correct bit is set.
- Fixed joypad registers to send joypad input only from the first controller.
- Fixed HiROM mapping.
- Added Mode 20/21 ROM Access Speed.
- Fixed a bug with the INC/DEC opcode that was previously returning the wrong
(This fixes Super Mario Bros 2's glitch where the character suddenly warps to the
top of the screen)
- Fixed messed up colors when in 256-color palettes.
- Fixed fading to use always the brightest fade color per frame
- Slightly improved VRAM allocation for background graphics
- Implemented Mode 7 Graphics

- Added more configuration options:
SMART - Don't allocate for disabled BGs
may see less garbled graphics,
slow refresh on every enabling/disabling/flicker of BGs
FAST - Allocate for disabled BGs
may see more garbled graphics
fast flickering of BGs (needed by games like Megaman 7)

- Added Quick Configuration Feature:
o L+R+SELECT+UP: Cycle through the following BG Priority Sets
set 1 = (P1, P2, P0, P3)
set 2 = (P2, P1, P0, P3)
set 3 = (P0, P1, P2, P3)
set 4 = (P1, P0, P2, P3)

o L+R+SELECT+DOWN: Cycle through the FORCED BG MODEs
opt 0 = as required by game
opt 1-7 = the respective modes

And expect the follow up on SnezziDS by Gladius

Awesome work as usual bubble2k :D. Yes, I will be porting this, but not until tonight - work calls.

New VBA Build From Spacy Released

Spacy has released a newl build of the Gameboy Advance emulator VisualBoy Advance. Here is the recent changes from him and PokemonHacker.

 I extremely reworked Direct3D to be faster than DirectDraw, but with the disadvantage of not being able tos cale the iamge with an aspect ratio, and the iamge is always bilinear scaled, like in DIrectDraw.
 Removed Skin support (from the Visual Studio 2005 build [#define NOSKINS]) to make compilation easier.
 Fixed joypad configuration dialog, it now responds faster to key presses.
 Merged the "open file" code for GB and GBA games.
 Merged the simple copy Image routine between DirectDraw and Direct3D, added a fast C alternative
 Worked over the whole DirectSound interface and found+fixed a minor bug.
 Enabled SSE(1) optimization in compiler

Pokemonhacker: [the one and only :)]
 corrected a compatibility problem with other versions.
 fixed a bug for ARV3/4 rom patching codes.
 corrected a bug when you entered a 'unknown' code, and then removed/disabled it.

GBA.cpp / gbainline.h:
 tweaked the bus prefetch a bit.
 changed the save handling a bit.
 added a 'master code' support (so the cheats are executed only when the master code address is reached ; if no master code are entered, cheats will be executed after each frame).
 corrected the mirroring of Vram.
 changed slightly the emulation of gbasavetype.

 vba now ignores rtc command 0x64.

 added a 64k->128k 'auto upgrade' (could correct some of the pokemon games's corrupted/deleted save problem).

 corrected a compatibility problem with other versions.
 fixed a bug for ARV3/4 rom patching codes.

 added support for swi $d (GetBiosChecksum).
 corrected a bug in registerRamReset.

 optimised/simplified a bit the bus prefetch handling.

You can get some more information and the release from their forum post over at NGEmu's forums. Also if you do give this build a try please report all problems to Spacy and other feedback you would like to give. :)
