DirectPadPro, CX-40

[NoahsMyBro]

Have any of you guys used DPadPro and connected a CX-40 to your PC?

 

I cannot get it to work, and am wondering if anybody here can help.

 

The only deviation I've made from the schematic is the wattage of the 2 resistors I used. Radio Shack doesn't sell 1/8 watt, so I used 1/4 watt or 1 watt (I don't remember which) resistors.

 

My problem is that only the fire button is seen by the PC. Moving the joystick is undetected, either in the configuration of PCAEWin 2.6 or the Game Controller Calibration control panel applet within Windows.

 

Thinking I may have a faulty connection in my wiring of the adapter, I whipped out my multimeter.

 

It confirms a connection on each of the straight through lines, and where I'd expect a 10k resistance, it reads the resistance at 9.8-9.9x.

 

I wired the adapter for the 2-button Atari/SMS sticks, assuming I could use 1-button sticks with it. I've tried 2 CX-40s, and an Epyx 500j with 2 buttons. I've tried using the LPT port built-in to my Dell Dimension 4100's motherboard, as well as one of the LPT ports on a Siig CyberPCI dual parallel-port card.

 

Only the fire-buttons register in Windows.

 

Do any of you know what's wrong? A coworker explained to me that the wattage of the resistors (they don't meet the spec) should have no bearing on how they affect the circuit's logical performance, & I'd expect the resistors to only affect the fire-button functionality anyway, and that part works fine.

 

If the resistors are causing the problem, where could I find 1/8 watt resistors retail?

 

Hell, while I'm asking, does anybody know where I may find .39ohm resistors to repair a Dreamcast with broken controller ports?

 

Thanks,

Steve
