The Dolphin emulator for the ps3 would be amazing or Nintendo 64 (Parallel N64) because Parallel is not OpenGL dependent.
The PS3 will never emulate GC/Wii, it's not remotely powerful enough.
N64 may be more manageable, but nobody has really worked on any N64 emulator since like 2012 or so (AFAIK).
There was some semi-recent developments in regards to running Linux with full hardware acceleration (probably about a year ago?), that would probably be the best bet for an N64 emulator port that's actually playable. But the Linux build will still need a lot of work before that's even feasible, so it's unlikely to happen any time soon.
You're better off using a PC if you want to emulate both.
LOL I´m using a slim but seeing as Parallel N64 core is not openGL compatible its surprising that it´s not been optimized (or even used) for the ps3what? people are actually still working on N64 emulation for PS3?
a little late
i would like to see it just to see how it would run but i would never use it because i never use my PS3 because i have a fat and it heats my whole house up 10 degrees and sounds like a helicopter is landing on my roof , if i am going to run it won't be to emulate N64
