there would be if it was TAS or something but we dont need that yettoo many variables to bother starting imo,
u just open 2 pj64 windows or w/e emulator ur using, u make sure both dont pause the emulator with the window goes inactive , u load SSB (U) on one , SSB (E) on the other , start a training with the same characters and there you go , u test every move on both windows with the same keyboard/controller
we dont need super accurate frame by frame **** yet , thats for later
