Thank you for the compliments.
When I wrap this baby up I plan on writing a "post-mortem". I've discovered little things here and there along the way and still am discovering more. Little things people might not think of...
For example... My P1 joystick is too close to the edge of the cab. My hand sometimes touches it. I'm currently using short shafts. I should probably use my long ones. Especially if I am to use these in games like Assault or Battlezone.
Also, for strictly 1 player 1 joystick games, I should configure them to use the P2 joystick. The P2 joy is closer to the middle, so for a game like PacMan, it would be better suited than the P1 joystick.
This will lead to confusion though, for anyone who doesn't know how I've configured it. I find already that people don't know what button to use.
