Just fixed the sticky cursor issue that draws even if using the d-pad. I think the repeat should be handled at the emulator level, ideally it could not even repeat.
Oh right, sorry it's kind of confusing, but I mean uxn emulator, on the GBA. The gba rom is basically a uxnemu wrapping a uxn rom, I meant, that bd should handle the key repeat at the uxn emulation layer, not at the gba emulator layer ;)
