I have released firmware 1.4 for all known revisions, including the new 2.1 units with a JZ4760B processor.
What's new ? Well compared to last firmware releases, mostly minor fixes and performances improvements !
Firmware for 1.0S units now have a fixed version of GPSP. You can load/save one save state, and exit it properly. The menu is fairly basic right now for those units but will get improved. Because i got no reports whenever it works on 2.1 JZ4760B units, those still use the older regba & gpsp binaries.
Picodrive got much faster, thanks to A600, and it even got faster than that with PGO. It should be able to play most Megadrive & Sega CD games at good speed. (Well except for 32X and Virtua Racing for the Megadrive...)
PocketSNES also got much faster thanks to PGO. While it's not silky smooth for some games, it's definitely better than before.
FBA-A320 no longer uses the crappy GUI that wasn't workin and instead uses GmenuNx's file browser. It's also much faster for CPS-1 games thanks to PGO.
Wizznic & OpenJazz finally got fixed, thanks bitrider !
GMU was also compiled for the RS-97, again thanks bitrider ! Note that if you have any issues with it, you can still use FFPlay.
Ohboy & Gambatte both got fixed TV Out, and maybe some minor speed improvements. No other changes.
Cavestory should run smoothly now. CW & TW versions were removed for the time being due to time contraints. Might get re-added later via SPs.
Oswan should be fixed over TV out now, in addition to being maybe a hair faster. Also, save location got changed.
Older firmwa releases might get a service pack.
EDIT: Fuuck, i noticed a last minute mistake. GmenuNx's text have changed but not the buttons themselves. I'll issue a minor fix for that.
