Update RetroPie-Setup script and install experimental/mupen64plus-testing. There will be at least two new rom folders /rom/n64-gles2rice and /rom/n64-gles2n64. Use gles2rice for zelda games. Use gles2n64 for mario64, mario kart and super smash brothers.
Mupen64plus-testing is broken atm but should be fixed soon.
