Super Mario World and DK Country on SNES seem to work perfectly. However when I tried Mario Kart 2p there was a lot of both video and audio lag (tested before I edited the memorysplit setting from default).
I would also like to try some N64 games, specifically Super Mario64 and GoldenEye (pref 2p), but as the PSX performance was so bad I don’t have high hopes.
Is it possible to run PSX and N64 games smooothly on the B+ RPI? Can I tweak my settings further for better performance? How much overclocking should the B+ be able to handle?
I wouldn’t count on the n64 running smoothly on anything but a pc and even then emulation suffers on some games. You can tweak settings and plugins to get some games working but there is only so much you can do even with a pi 2. That being said I definitely prefer a pi2 over my B+.
Even with a Pi 2 I can’t get 99% of my N64 games to run half decently. Super Mario 64 and Mario Kart run okay but honestly not good enough to where I can fully enjoy the game. (And yes, I’ve tried everything under the different emulators and overclocked.)
Goldeneye in particular “has issues” in the compatibility list and it is currently completely unenjoyable to play in single player so I wouldn’t even want to know what it is like with four players.
On the other hand, PSX on RPi2 is a way better experience and I haven’t encountered any games I would consider unplayable.
