Just the normal MAME neogeo bios should do the trick. If it doesn't, i'll list the exact roms you need. and for neoragex, the default settings can allow bits to get skipped on a fast computer. use these settings instead: Video Options: 16-bit, No, No, No, Yes, 0, Yes Audio Options: Max, FM/ADPCM, Stereo, 16-bit, 44 khz, No
