If the cartridge is completely corrupted but you were able to backup a save that still works with pkhex, you could get a new cartridge and manually edit in your original cartridge's data (OT, playtime, etc) shown on pkhex and drag and drop your uncorrupted pokemon onto the new save. Or use an emulator to play your backed up save.
