Hacking Gateway Game Backup Question

[Skeet1983]

For backing up my 3DS games with GW, does the game have to be certain required Firmware? I mean, if the system is at a lower FW and game requires a higher one, it would not work? I am worried because one of my older games (Bravely Default) backup failed, don't want same thing to happen with upcoming Mario & Luigi Paper Jam (Already pre-ordered game and paid for it in full). Thoughts/help on this issue/concern GREATLY appreciated

Nope. Just back it up.
