I was hoping that RetroArch would be the last emulator app I ever needed but it's looking like platform specific emulators are going to be better in the long run.
Dreamcast - Reicast is pretty obvious
Mega Drive / Genesis - no idea.
Game Boy / Game Boy Advance - no idea
SNES - I always used ZSNES before, bsnes (now Higan?) appears to have reached 100% compatibility but I'm not sure what that's done to performance. Maybe I'll start there and keep an eye on performance and battery and swap it out for snes9x-next if I need to.
NES - No idea. FCEUltra was my PC emulator
Playstation ???
PSP I'm not even sure if there's a point. What PSP games do I miss. Crush? Jean d'Arc? Loco Roco?
