Alternative Genesis Core with ARM support.

A program can tell that it's running on PyBoy because the buttons always change right at vblank.

To reproduce:

1. Install PyBoy
2. Start the test ROM "Telling LYs?" (which I have precompiled for your convenience here)
3. Press all 8 buttons in any order
4. Watch the arrow sprite at the right side

Expect: Arrow moves after each press, followed

• Organize rules better, possibly with "section markers" (`// -

"LOW" and "HIGH" are used to refer to signals, but a software developer may not have the necessary background to understand what those mean. They should be at least explained in an info box at the top (as per the style guide), and maybe replaced throughout the document where it makes sense to do so.
