Hardware Homebrew that restores save files to GBA cartridges

[Awdofgum]

Hello everyone,

I'm trying to help a friend out, who's lost all of his progress on a GBA game.
Is there anyway I could restore a save file to his cartridge through my original NDS and an Acekard 2?

Thanks,
Awd


Edit: I've tried eepinator and the GBA_Backup_Tool and I haven't been successful.
Edit: Oh okay, there was just dust in my slot-2. I got it now.
