mmmm... didn't have as much luck with mine. Had issues with king of fighters millennium and strider 2, which are both from 1999 I think. Also mr driller I had similar issues with performance. I also had issues with street fighter alpha which was a few years earlier, 1995 I believe.
KOF Match of the Millennium was a NeoGeo Pocket Color game. Capcom vs SNK, Capcom Vs SNK Pro, and Capcom Vs SNK 2 :Millennium Fight 2000 were based on Naomi (Dreamcast) Hardware, not MVS.
Mr.Driller ran on Namco System 12 hardware , which is an upgrade from Sony's PlayStation-based System 11, the MIPS R3000A microprocessor is 50% faster, and the C76 sound processor is replaced by the H8/3002. But its just a glorified PS1.
Strider 2 ran on the Sony ZN-2 platform (aka System 16) which is just another improvement over the playstation hardware (more ram, medium res support, etc)
