The reicast emulator is more a proof of concept on raspberry. The hardware is to light for run correctly Dreamcast. It's why we doesn't had reicast or psp emulor. It's just good for "e-p***s" now. Not for gamer. (I have retropie installation to, Eighkiller ;)). For me i hop an a good support of mario tennis on N64. That is more possible :).
