Gah. Seeing as I couldn't find where this would be relevant, I'll post here. (Perhaps this post should be stickied, so that all unsorted data doesn't need it's own thread or something?)
Here's the location of the "Level" information on the Status Menu (FFIVET with no header, I'd imagine this is the same for FFIVj):
$01DC32 - The number here determines where in RAM the "Level" characters are stored. Originally set to $01F0, when set to $0092 it stores where I currently have it store (after the character's name).
$01A9CA - The number here determines where in RAM the number following "Level" is stored. Set this to $00DE. (actually, this location is for the instruction LDY #$xxxx, I forget what the original was. I set it to LDY #$00DE).
