Basically I have the full .144 set the roms that work. I only play a handful of games so I moved all the roms i play to a temp folder then moved the roms folder which only has games i don't play out of the mame folder.
Then renamed temp folder to roms.
So most games work but some don't. I Figured out neogeo games need the bio's rom. I added that and now they work. But what about games like pacman which was working before i moved it??? as far as i can tell it needs nothing else to run but i still get the "selected game is missing one or ......"
Also the simpsons, tmnt don't work...
