So I am about 99% finished with my mammoth project of building a Donkey Kong mame cabinet from scratch. Everything is looking great and running smooth with the exception of Donkey Kong, the one game that SHOULD run on this thing.
Currently I have almost 250 games up and running including many Neo Geo games (metal slug series, money puzzle exchanger, kof, etc.)and 80s Era games (Pacman, tapper, donkey kong Jr) but the original Donkey Kong runs very very slow, around 15fps?
The computer I'm using is an old Windows XP machine, unsure of the processor at the moment. However, given the fact that so many other games are running just fine, I don't understand why donkey kong continues to give me problems? Any suggestions from the group on things I can do?
