Its saved as a dexdrive save which features both a backup done with the Action Replay Pro (GameShark Pro) and a save done with the SRAM Manager 2.0 by Blackbag. Use the restore option in the Dexplorer else the extentions will be lost and you probably wont be able to use the saves. Note that when you use the restore, everything on your controller pak will be deleted to make room for the restore. So it might be a good idea to backup your controller pak first ;)
