Ont he Wii-U version of this, you can remap every single (Non-directional button) in the Wiii-U controller settings. I have mapped my left trigger(classic controller pro) to the GBA's Start button, and it has made it significantly easier to pull off a zip.

What do you all think about allowing this in official runs, especially since this is mostly run on Gameboy Player GBA?

Thanks!

If mapping is a official function, I think it should be allowed. I'm playing on Gameboy Player just because of less input lag.
