I am playing Pokemon Theta Emerald EX on my 3ds with FBI. I used the Ultimate GBAVC Injector program to convert it to a .cia and installed it on my console. I have been playing for quite a while when I reached a certain point in which I a trainer blocks my way (route to the right of Lilycove). This trainer is unavoidable, and she has a Missingno on her team. This Pokemon is level 0 with 0 health, and attacking it makes the game freeze. The only way I can see to get around this is through cheat codes, but I am not sure how to use said cheats without damaging my save file. Any ideas?
