Well, after much research, I have concluded that it is a reproduction and that the game is saved in the sram, so I used your tool and I was able to get the sav, but how is the sav injected back into the .gba , I replace it with hxd?
hello, i have the same problem with pokemon emerald. I extracted the sav with gba backup tool and when i put it in PKHeX it say me the size is invalid or binary is not compatible with save. Here is the save file in case you can take a look at me. Thanks
