Neogeo On Dc ?
 

THERE IS AN EMULATOR WHO DOES THAT ?

Apparantly so, I have one but have not yet tested it (run out of disks! See other posts...)
Try Kazaa.

(Apols to moderator if this is telling where to get ISOs..!)

Well apparently, the Dreamcast doesn`t have enough memory to load games such as KOF. Lighter games work however, but not quite at full speed. (about 80% speed from what I have read)

However, that`s a shame that no emulator was release to emulate NeoGeo CD which would not suffer from such memory limitation.

try MDCNG2.7
it is available on dcemulation.com
