Psychopad KO to parallel port

[jrcmilanez]

Hello guys,

Yesterday I tried to interface my Psychopad KO (act labs) to my parallel port.
So, this arcade joystick supports Playstation, Saturn and SNES. To do this, you need to change the cable between the control and the console.

Unfortunally, I don�t have all cables. I only have the Saturn cable. So, I started to made a interface for it. I used this diagram:
DirectPad Pro

After made it, the joystick doesn�t work with NTPAD driver and with PSXPAD driver too.

So, what to think? This arcade joystick have a huge circuit inside it, with a PIC to do programable moves, rapid fire, etc... I think the parallel port cannot supply this circuit, because it have a lot of devices inside. What do you think, guys?

I think I should put an extra power supply on it, but I don�t know where to connect. Somebody can help me? I would appreciate!

Thanks
