I used Project 64 v1.5. It has a cheat selection at the top. I was playing Super Smash Brothers, I was messing around with those cheats when suddenly all the characters can't run or jump. Can anyone help me with this problem? Please!!!
Not sure what cheats there are for SSB but uncheck all cheats in the cheats field, it's very possible that you checked a cheat that doesn't allow running and / or jumping.
