Subject: Eliminate the latency of button press recognition, which was bad
 enough to lose keys entirely sometimes, and could otherwise delay a button
 press or release by 200 ms.

This was the entire reason I created the fork, and I finally did it! It syncs the controls every scanline of a frame, which costs about 60,000 MIPS instructions per frame to deal with. Luckily, the processor runs at 396 MHz, which means the cost of checking the controls is 1% of the CPU's power.
