I think broken trace might indeed be the issue. I bought bad boards from him before, and it wouldn't be the first time, unfortunately. I just have to get my magnifier out and start looking at all the PCB traces.

Standard controllers work fine on both of our consoles with all number pad buttons registering. This is mainly an adaptor for being able to use the twin analog sticks on Playstation 2 controllers to play twin-stick 5200 games like Robotron 2084 and Space Dungeon. The jumper pins to the upper right of the PCB are for using a USBasp programmer to program custom hex code to the on-board I/C. Continuity of the cables is a non-issue since I have tried it with two different DB15 extension cables at my house, and my friend had the exact same result with his DB15 cables at his house in another state. My suspicion is that the hex code developed by Dr. Scott Baker is somehow flawed.

Here is an image of the Dr. Scott Baker PS2 to 5200 controller adaptor: As you can see, it has its own PCB, and does not use the original stock 5200 controller number pad flex circuit. Also, I have my doubts about a DB15 cable wire being bad, because my friend lives a state away, and we both saw the exact same issue with our own unique setups, adaptors, consoles, and cables.

Thank you for replying. Do you know which pin number of the DB15 connector affects the number pad button inputs? The odd thing is my friend and I get the same result on two different consoles with two different cables.

About a year back, I bought the PCB's and components to make two of Dr. Scott Baker's PS2 to 5200 controller adaptors for using both PS2 analog sticks on Space Dungeon and Robotron 2084. Being wowed by the experience of playing these games with the PS2 Dual Shock controller, I took little time to check out full functionality. My friend who I made the second adaptor for just recently noticed that none of the number pad buttons register inputs in either game on his two port 5200 console. I then tried it on my own two port console, and sure enough, none of the number buttons, * or # buttons, register inputs to these games. I have tested both adaptor assemblies with my multimeter and register continuity on all twelve number pad buttons when they are depressed, so the components are, in fact, good. Has anyone seen similar behavior from their SM Baker controller adaptor, or have any idea about what is possibly causing this issue?
