This turned out to be a bit trickier than I thought because the mini-expander schematic doesn't show which pins the port bits are connected to. I managed to figure it out from a photo of the PCB and a post by jaybird3rd. Then I 'just' had to map the Micro-expander's 20 pin connector pins to the D9 joystick socket.

The cable is reversed on each side of the 20 pin IDC plug, so the colors are the same for both joysticks. If you only have one gamepad or joystick then only the right-hand cable and D9 socket are required. Photos below show the adapter I made for Aquarius gamepads. An Atari joystick cable would be the same except for connections to the D9 sockets. I also made an Atari joystick adapter with the 20 pin plug and D9 socket connected via a small piece of matrix board. Using this I was able to play some games with my joystick, but Night Stalker needs 4 buttons to fire in different directions (perhaps it can be hacked to work with a single fire button?). Is this correct? Are those pin numbers for a male of female connectori? Edited August 21 by utri007 Quote Link to comment Share on other sites More sharing options...
