wonderful game corruption

[xcr03]

so i was playing fire red with my friend. i wanted to catch up to him and play so i used a rare candy cheat and a ghost cheat using gameshark. i passed through the lab to skip getting a starter and i used a cheat to get hitmonchan. (note to people who dont use gameshark: this usually wont crash the game) so i got my hitmonchan and taught it mega punch while naming it saitama (lol) and then after that a bunch of walls were all over the room and before that i disabled cheats so i had no idea what was going on. i went outside of the house i was in and everything was normal so i went to go and battle some trainers. my lvl 67 hitmonchan decided to become a lvl 5 (?). he knew tackle and growl. so i went to my pokemon and none were there but one that was glitched at the cancel button. it looked like a shiny bulbasaur so i decided to click it. it became a lvl 213 nothing. and my game crashed XD
