Hello there,
A few years ago I tried to do some trading on my emerald(legitimate cartridge) by using gba back up tool to put it on the computor and then trading through an emulator, and I remember having used pkhex on it, but whenever I try loading it back on to the cartridge it says that the save file has been erased due to corruption or damage. This had worked multiple times but now it won't, and the save only works on an emulator now. Could someone help me to fix it? I would greatly appreciate it.
The save is attached below. (And some other versions of it).
