Q: Do you have more information on the joystick you are using? And how you hacked it to work?
A: Since the Mamebook was done on a whim, I only used stuff I got at home that required little or no hacking. I didn't want to bother with I-pac and wiring so I decided to use one of my old Namco Arcade Sticks and a simple PSX-USB adapter. I also used USB Overdrive to sort out the mapping. Piece of cake!
