To evandixon: you might want to update your original post a bit. Not only are the websites for Console Source and reichi down (at least as best as I can tell), but we don't have any confirmed way of successfully backing up and restoring X and Y save files, even when it is just restoring a save backed up from the same cartridge (let alone a different cartridge). Whatever they've done to encrypt the saves and/or flummox save game backups, it is effectively impossible, at least for the time being, to back up and restore Pokemon X and Y cartridges.
(Also, for anyone who doesn't already know, digital is not an option - the feature is disabled for X and Y, and Nintendo has systems in place to make manually restoring old save files from digital games largely impossible.)
It would probably be prudent to have this on the OP, lest anyone physically alter their cartridge for no reason, purchase products that are currently useless for Pokemon (with no guarantee of future compatibility), and/or risk their save data, game, or system getting damaged.
