These are the settings used in the official Nebula 2.25; I've left out kof2002b as it doesn't work. Typical [system] paragraph: CartridgeID: 265 GfxCrypt: 2 GfxKey: EC PCM2: 3 ButLayout: 9 Fix: 1E CartridgeID: the cartridge number, located at byte 108 of the p1 rom. Probably has no effect. GfxCrypt: 1 = kof99 decryption, 2 = kof2000 decryption GfxKey: the "extra-xor" for the GfxCrypt PCM2: The decryption method of decoding the v roms ButLayout: I guess this is "button layout". All games = 9, except 8 = vliner, vlinero, 7 = jockeygp Fix: The "driver_init" to be used.
