Propeller-based NES Gamepad

Hi,
I just turned my $80 Propstick USB into a ($5?) NES Controller
- 8 Buttons to inputs 0 to 7 as described in the Education Labs
- 5V and Ground from my almost-a-demoboard-protoboard
- 3 Datlines with pulldown resistors connected between the props on both boards
- some lines of spin:
·This is what it looks like, chaotic wiring, I know...
I tested it with Dodgy Kong and it works!
However·I had·to uncomment the "Delay(1)" lines in the NES_Read_Gamepad section of the sw_dkong_020.spin and add a delay function:
I know, this is bad coding, but I just need a tiny delay and hope I'll manage to write an asm driver, so the delay will not be necessary at all.
I realize that this is another one of my foolish projects, and a prop is total overkill for this task, but think of the possibilities:
- One could replace the buttons with sensors and play hydra-games with acceleration or ir sensors
- One could build a wii-controller-to-NES-converter and play NES games with wii-controllers
Cheers,
Clemens
Oh and thank you Steve and Eric for Dodgy Kong!!!

I think there was an article in Nuts & Volts a few months ago about using an accelerometer as an input to the Hyrdra, my mind is fuzzy though.
A WII to NES converter would be cool!
