DISCLAIMER! i've never tried this, and i'm fairly new to the 3ds flash cart thing too. i dont think this will mess up saves, but i'm not responsible if it does. i'm a big pokemon fan like many on here, and like some i have an interest in pokemon and item duplication. in previous gens, i've usually done it with save file backup/restores rather than sharking or shutting off when saving. less chance of issues. in hearing how the gateway holds and saves its save files, i realized that it maybe possible to easily, albeit slowly, clone some pokemon and items. unfortunately, the method i have in mind requires 2 3ds systems and 2 games, i only have one system. because the gateway save is not backed up to the sd card unless the system is shut down properly, you could possibly trade pokemon (or pokemon holding items like a masterball) to a second system, then PURPOSELY shut down the first system wrong so the save file won't be backed up to the sd. from what i've read, the save is still held in the gateway card itself however, so a different game must be loaded and then shutdown first, so that the save file on the card is overwritten. then, once pokemon is booted back up, it should conceivably be the save from before the trades, which is still on the sd card. thus, both systems will have whatever pokemon and held items were traded. regretfully i dont have 2 systems, so if someone that did wanted to try this and post back if it works or not, that would be great. as stated above, try at your own risk.
