Hacking GBA Backup Tool does not inject a .sav to my cartridge

[white187]

Hi guys!

I have a problem trying to inject a .sav to my Pokemon Emerald.

The problem is that if I extract the .sav to my SD card, it extracts correctly, if I try to inject this .sav back to the cartridge it does

But the problem begins when I extract the .sav to the SD, I pass it to the PC, and at the moment of injecting it to the Pokemon Emerald, it gives an error that says

"Data transfer failed. Please do over again. (A): Confirm"

Being totally impossible to inject this .sav to my game. I also tried to inject a clean .sav that I saved on my PC directly from GBA Backup Tool, that is to say, without modifying it, and I still get the same error.

I resort to this forum to ask, because I am completely desperate. If I don't fix it I think I will have lost my saved game x)


I leave a screenshot with the error I get

I'm sorry for the console issue, it's already many years old and it's destroyed
