>>19186495>How game-changing can it be?Not much, since you currently can't remove the glitch moves (Game crashes upon seeing the moves).
Doing this in a speedrun is too time consuming, and even then you would have to train a level 5 Pokemon all over again.
It also currently can't hatch into anything with a higher index number than Minun (He says it's theoretically possible, but so is catching a 6IV ditto outside of friend safari) , so you can't get Jirachi and Deoxys, if you crave that full 3rd pokedex.
Also, the old R/B/Y mew glitch is pretty simple, this one is too complex.
