Hacking Save Data Backup Before Field Runner Downgrade

[Magic Lubricant]

Hey! So I'm going to downgrade a 11.0.0-33 new 3ds. I got a entry point to backup my save data but I'm having some problems. When I try to run JKSM and select a game, for example Monster Hunter Generations or Rhythm Heaven Megamix, it gives me a black screen on top, and a red screen on the bottom, any idea why? Also, just wondering, if I backup my save data using the native way, can I restore it on a different 3ds?
Thanks!
Edit: Anyone know how to backup Rhythm Heaven Megamix save data using homebrew?

Here you go. Keep an extra good backup somewhere please. I gave it a quick test run and gave myself 99 potions, but you never know. It exports to SD:/MHG. If there's any issues, I'll try to fix them ASAP, but I need to sleep.
