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?
