This is how my rompath looks like in mame.ini: rompath 'roms X:\Roms\MAME 0.234 ROMs (merged) X:\Roms\MAME 0.232 CHDs (merged) X:\Roms\MAME 0.234 Software List ROMs (merged)',ītw, my default command line parameters for mame in LB edit emulator is '-keyboardprovider dinput aes %romfile% -bios japan', how to make mame favor usa/world region? usa/europe instead of japan cause warning message when launching a game 'One or more roms/CHDs from this machine are incorrect.'. Anyway, i put the latest neogeo.zip (bios) from 'MAME 0.234 ROMs (bios-devices)' inside the neogeo AES roms folder, run games but the sound issue remain. If neogeo.zip is required for my merged set then how come the AES games run in the first place? The SL Merged AES full romset is from pleasuresdome. It is the Non-Merged set that has the bios included in the actual game rom zip file. If you have a complete rom set then you do have a neogeo.zip file and if you don't have one you will need to find one because it is required for Split and Merged sets. download 127 Files download 126 Original. All Completed AES Exclusive Neo Geo Games Released in Japan and North American Addeddate 00:32:52. Merged sets do not have the bios included in the actual rom files. snk, neo geo, neogeo, neo-geo, rom, roms, aes, romset Language English.
