I was able to extract the SAV with a tool shared by Slayer in another post, but the GBA Backup does not inject them, I suppose we have to join it again to the fake cart rom
This is the SAV file that I am trying to use in the PKHeX but I get that alert, attached photo of the sav extractor (GBA Bakcup)
POKEMON_FIRE_BPRS00.sav
Good afternoon I am trying to use the PKHEX to edit a game that I extracted from a gba cartridge using a DS LITE with GBA BACKUP, but when trying to open the SAV I get an error, I am doing something wrong?
