Tried installing from source using retropie_setup.sh but the results are the same.

[quote=109136]I had Mariokart working perfectly with retropie 3 but once i upgraded to 3.1 no matter which emulator i boot in too the menu screens writing is distorted. the game still plays fine if you manage to navigate the blurry menu. has anyone got mario kart running with retropie 3.1? need help

Your issue is probably unrelated. I am unable to load any game using the mupen64plus emulators and am on RetroPie 3.2.1.
