dude, you're awesome, it worked, and so are the rest of you, we have to jot this down, it only works with older versions of mame at this point, thanks once again belgarath
.I just wanted to chime in and say that this does work with the latest MAME 0.206 (don't want to spread false information). A few versions ago there were revisions to the neo bios file so maybe your bios rom didn't match the version of the emulator you were using but whatever the issue is its on your side not with in MAME.
