I have no idea why this was a thing (do people store this repo on FAT32
flash drives or something?), but quite a bit of files had a permission
of 755. This isn't really a problem, but it's inconsistent and weird.
It seems to be used as the "big" text entry cursor (i.e. for the bottom
3 buttons in the text entry screen).
It is never referenced explicitly, instead used when adding 1 to
SPRITEANIMSTRUCT_0E, in NamingScreen_AnimateCursor.
