Hey everyone, so I played through Pokémon Emerald in JP and uploaded the save to my Eng Emarald. I went to edit the trainer info so the name is in English, however whenever I hit save the name just gets erased and ends up being blank. I uploaded the save to the cartridge and everything I edited was good except for the Trainer name. Any solution to this or am I screwed because the save is originally Japanese and can’t be fully edited due to it not being in the original save files language?
