I just backupped my Saves from about 10 3ds cards. I was really careful, using the latest Firmware 1.3 (of the Save Dongle) and Software Verion 1.5 to do so. I was always waiting until the backup process was really complete. After backing up the 128 K Save of Paper Mario, the data on the card was corrupted as i started the card again with my 3ds xl. The save of Zelda was also corrupted, but - thanks to god - after writing the backup save a second time to the card, it was working again. I then tried it about ten times with the Paper Mario save - but no success... There are no Paper Mario Saves in the Database of the Save Dongle Homepage... is the Dongle no longer compatible with new 3ds cards?
