New user and a happy customer reporting in! I modified my gameport CH Combat Stick with rel4y’s upgrade board and shift register. See attached pictures for the result. Please ignore a few wrongly connected wires in the other picture. I corrected them after taking it. The MMJoy configuration seemed a little daunting at first, but I got it working after a few attempts. Thank you, rel4y for an amazing product and for the help and support!
