I have a Microsoft SideWinder Game Pad (Part Number: 90873) that I want to use with my Raspberry Pi RetroPie. I have the pinout and want to replace the GamePort end with USB. I followed the instructions here

GP1  --> USB Red  
GP4  --> USB Black  
GP10 --> USB Green  
GP14 --> USB White  
GP2  --> GP7

and I have power, but the Raspberry Pi won't recognize the controller, and it seems like there are a lot of connections missing. Can anyone help with this?

    Your linked instructions are for a Precision Pro joystick, not a Game Pad. – Nick T Jan 11 '15 at 7:04
  • It's my understanding that GamePort is the standard that a bunch of controllers follow. Precision Pro and SideWinder both use the GamePort connector, so should have the same pinout – Thomas Jan 11 '15 at 19:16

This 'hack' will only work on the Sidewinder Precision Pro joystick. From WikiPedia:

with the widespread introduction of USB in consumer computers shortly after the Precision Pro was released, Microsoft soon re-released the joystick in a USB-compatible form (joysticks labeled as Part No. X03-57540, Product I.D. 85791-...[8]). The revised joystick still featured a gameport connector but had additional circuitry for interfacing with USB, and was bundled with a USB converter

I will not work with any other gameport device. You need to buy a "USB Gameport adapter."

  • Thanks! Maybe I'll look into a way of interfacing with Arduino. Or just buy a different controller lol. – Thomas Jan 11 '15 at 19:10

    @Thomas the GamePort is extremely simple; it looks like you could emulate it with 4 GPIO (digital) and 2 ADC (analog) inputs. If you can get by with a D-pad, a little extra circuity could easily turn the two analog channels into 4 digital. Though it would be easier to just hack up an NES controller (requires no extra circuitry). – Nick T Jan 12 '15 at 1:02
  • Thanks Nick. I'm kinda just getting started. Do you have a link to where I could find more information on how to do the emulation? – Thomas Jan 25 '15 at 4:42

I Have modified several Microsoft Precision Pro Joysticks. The USB to Game port adaptor is a.F3U200-08inch made by Belkin and can be bought on Amazon for less than $10.00. However here is the tricky part. You must make a "Jumper" wire using a small wire usually found on a "Wire tie". you have to "Jump the wire from Pins 2 to 7 on the Joystick. Strip only the part of the wire that will go over the pins. I used a very fine pair of Needle nose plyers for this operation.
