I was working on a track today when my batteries suddenly died. No big deal, head downstairs and grab a new set. I turned on my gameboy and fixed all the errors and shit, changed the Key Delay/Repeat back to 7/3. However, it still only lets me move 2 rows/columns per button press. I swapped the cart from my other gameboy and confirmed it was an LSDJ problem, not a DMG problem. This is pretty annoying, and I'd rather not have to work on all my songs like this.
Any help would be much appreciated!
