A huge update for the roms section as of yesterday! We now have 2,000+ MAME ROMs available for MAME4All/MAME4Droid, the rom set is 0.37b11. For some reason, the size is showing NAN, please ignore this as it's a minor bug with the website, not the ROMs. This romset should be ready to go, however if you have issues look below:
MAME4droid uses only '0.37b5' and 'GP2X WIZ 0.37b11 mame romset'. Use "clrmame.dat" file included in /sdcard/ROMs/MAME4all/ to convert romsets from other MAME versions to the ones used by this version, using ClrMAME Pro utility, available in this URL:http://mamedev.emulab.it/clrmamepro/
