#40 SNES/GC Controller Support

[prattt]

Support for SNES Mouse (via GC adapter) and GC ASCII/SAMMY keyboard.

SNES Mouse buttons work, but the mouse ball values are messed up.

With the GC k/b, the controller side of it works (one of the plugs), but the k/b side (the other plug) doesn't. I have links to old GC doco that covers the interrupt values etc for the comms protocol, and it's looks the same as the regular controller, just with different masks. My C isn't strong enough to get it working myself.
