For the past day, I've been trying to use PKHeX to edit my Fire Red Cartridge, using a DS Lite and an R4 Cartridge. I first used GBA Backup to rip the save file from my game. After doing that, I put it on my PC and set PKHeX to FireRed, however, when I try to drag it into the application, it gives the error message "Binary is not compatible with safe file. Current SAV Generation: 3". Does anyone know what is wrong with the file? I've tried making multiple backups to have the same issue.
I've attached my save file here
POKEMON_FIRE_BPRE01.sav
As you can see, the file is 128k, which is the amount needed for Gen 3 games.
