Home Page Forums MAME MAME Regarding the gba driver

http://www.turboz.to/

Somebody should try to emulate this on our GBA driver ...

(Yeah, that's right, Sharp X1 emulator on Game Boy Advance, go figure ...)

with the amazing contribution by endrift and the coding by Arbee, the HBlank mechanism has improved a lot in the MESS driver for the GBA!

from a (very) preliminary examination of some games which were not working earlier, I can report that a bunch of games which were resetting or sitting to a black screen are now working pretty well

For instance, Stafy 3


DrillDozer


Rayman 3


Driver 2

other examples Sabrina The Teenage Witch, which does not sit to a black screen anymore


Ueki no Housoku, which has no more glitchy chunks of graphics


and, probably my favorite fix, Sonic Advance games, which does not play in slow motion anymore


plus some games have less flickering during emulation

the driver is not 100% correct yet (e.g. Mario & Luigi Superstar Saga is still glitchy, some driver games like GT Advance don't display the graphics anymore, and Dragonball Z The Legacy of Goku misses the BG graphics...), but the impact of the fixes added this morning definitely gave a big push to the quality of the driver

Thanks endrift and Arbee!
It's awesome to see improvements in this driver

GT Advance (and probably other games on that engine) is fixed now after a further tip from Endrift. No ideas on Mario & Luigi or DBZ.

great to see GT Advance fixed. HDMA fix from yesterday basically made playable any UbiSoft game which was broken in 0.160, including (in addition to the games showed before and to probably many more)

Prince of Persia Sands of Time


TMNT


and Splinter Cell


Also, The Sims 2 does not freeze anymore at game start


@Arbee: if you want instead a list of games which still have issues (same as in 0.160) you can add to the previous titles
- Madden 2006 & 2007 (but not the earlier ones), once you get in-game
- VIP, again once you get in-game

Mmh, somebody should check out if Gunstar Super Heroes is fixed at final level and doesn't hang anymore.

Also, just to post it here since it got lost in the shoutbox, the recent fixes seem to have fixed the demo "Matt Current" by Shitfaced Clowns, the audio no longer becomes garbage static in the second half of the demo. Though, I haven't checked it with the absolute latest fixes.

The VBL timing and HDMA suspension fixes do seem like they'd be responsible for fixing it, though, as I recall asking Kusma at one point what he'd reckon was the cause, and he said it would likely be because it was running out of time during VBL to run the audio player code. With proper VBL timing and no more HDMA eating CPU time, it seems like that would do it.

I'll give it a run tonight and report back

Grand Theft Auto Advance used to hang right before loading a game, now it causes MESS to crash after starting a new game with this error:

This happens right after this scene at the start:



I suspect that the game not working has nothing to do with the recent changes but something completely different and unemulated?
