I'm working on a simple personal hack of Fire Red, and I was just about to wrap it up when I noticed that the Pokedex graphics were messed up. The menus looked gray, and would display a glitched screen instead of the Pokemon's in-game location. Unfortunately, all of my backups/versions have this problem, since I only noticed it later on. The only thing I can think of that might've caused it was messing with the Pokedex Data in PGE.
Is there any way to fix this and revert the graphics back to normal?
