Super Smash Brothers : All Player Problem

[Talkalots]

when i activate the (have all players cheat) and then try to play a vs. game as soon as my cursor moves over the chars it tells me it has encountered an error and crashes to desktop

It's not exactly a new thing that enabling certain cheats can cause instability and crashes. Granted, this doesn't always happen to everybody.

well then just upgrade or try another emulator

Or maybe... JUST maybe you could actually try getting all the characters yourself.
