Alternative Genesis Core with ARM support.

There should be some basic automated tests for the gamepad support added in #164. I don't have a gamepad, and I imagine most contributors won't, so it'll be very easy to cause regressions. It is also impossible for me or other contributors to refactor/touch that code because we can't test it.

Once there are some tests, there are some refactorings I have noted in #164 that are probably worth doi
