I know Grand Prix Racing (or something like that) and Metal Gear Solid for PS1 are able to run with their respective BLEEMCAST emulators. I don't know of any other games (although there probably are one or more I've missed). Bleemcast is very cheap to buy even though it only supports one game for each release of Bleemcast. Check out Electronics Boutique at
