That is very nice, and would solve the problem of playing Revs on the TV perfectly.
I only have BBC Joysticks and a BitStick though. Are there enough free FPGA resources to change the joystick/config interface from shift register to IIC? I was thinking of an atmega* as iic target to provide the parallel and ADC input on the one chip.
I was also thinking of adding breakout for the 3v3 side of of the PS2 interface so that could all be done in 3v3 if bunged in the box with the keyboard.
