The plan is to:This doesn't benefit people who mainly use sysNAND, I assume?
- always prevent you from losing GBA saves (if I don't "lock" you to sysNAND, you'll lose your last save on a9lh)
- remain on the booted NAND/FIRM after a system setting reboot (but this can be overridden holding A - then hold L, R or nothing as usual, while holding A). This *only* applies with a9lh and a soft reboot.
