I have a hacked 3ds and a (soon-to-be-)hacked 2ds. I want to be able to play the same game, using the same save file, on both systems, switching between them at will. Presumably both systems could have different folders on the same SD card, and I could use JKSM to backup and restore the save file between the folders. That sound kinda tedious though. Is there an easier/better way of going about this?
