WARNING! Do not use on new2DS, because it's untested!
However, it should work fine on old3DS (even 2DS, if it's something you want for some reason), and new3DS.
Controls:
- UP/DOWN: adjust raw value
- LEFT/RIGHT: adjust by increments of 16 (0x10) in a weird way
- SELECT: exit
The effect is immediate after adjustment.
To unpatch, turn off your 3DS, then turn it back on.
