Anyone have any advice regarding my design? I'm figuring on playing older titles mostly so I think the 6 action buttons are more than enough to play on. That will allow me to map an A, B, X, Y, L1, L2 for console games. On the top row I can place a Select (player), Start (coin) as well as a hotkey button. That leaves me with an extra button at the top if anyone can think of what I can use it for. Also, I'm planning on one button on either side for a poor man's pinball machine.

I figured I'd ask here before mocking it up in case I missed anything.
