Is there a way to type KEYCONFIG or otherwise rebind on the 3DS?
With the physical matching layout (e.g. B/O/bottom left, A/X/top right) some games are harder than they ought to be, and other times it just sort of kills the fun.

E.g. in celeste, holding X to cling, then tapping O to jump can result in accidental releases, since your thumb goes up through the buttons at 90 degrees, rather than naturally along them (as it would with the standard platformer Y/B layout).

Less of an issue on e.g. the Gameboy, since the buttons weren't a at 45 degrees in a diamond shape, but it would be fantastic if we could do something about it here.

If there's nothing in the works, would you accept a PR along these lines?

Thanks.
