Using 3.5mm TRS Joystick with Edladdin Super CV PCB

[netrogames]

Hello. 

I built myself an ambidextrous fight stick that I use with the Xbox One and Xbox Series S with a Xbox Adaptive Controller connected by 3.5 mm TRS cables. 

 

I use it with a lot of systems with Brook adapters and I was glad I chose Xbox because that was the one that enforced its PCB the most.

 

However I got some systems that will not work with the adapters.

 

Most of them are addressed with using a 3.5 mm TRS to pad hack hookup where we pad hacked a Genesis 3 button joystick. 

 

From there we could go most pre crash systems.

 

One system there's no easy Genesis to X after is for the ColecoVision super action joysticks.

 

I could use RetroGameBoyz regular Genesis to clecovision adapter but that doesn't work for super action games.

 

For super action games I need an Edladdin Super CV.

 

I understand that the way Ed Laden designed it was supposed to be permanently hooked up to your joystick and the PCB looks like there's two separate grounds that should not be mixed up. 

 

However the problem is I have TRS cables, and Ed does not support TRS cables.

 

I'm having some weird errors when I'm plugging it into the Colecovision .  First plugging in one control does not make it work with just one control.  So I cannot individually plug in left and right and up and down and index and middle and ringing pinky and get isolates each of those. 

 

I could look at the wires but it's a big mess and it's kind of tough to trace it through.  Add to that the guy who put on TRS cables accidentally doubled the buttons because originally the double buttons was for mirrored ambidextrous joysticks.

 

However I noticed one flaw with the headline design that the TRS cables would fix if they do work correctly.

 

I'll discuss that flaw on a separate conversation but now  I'm having trouble wiring this thing because sometimes the joystick doesn't work sometimes the pad works sometimes the pad doesn't work I know this when I plugged it in it was Y cabled to the Xbox adaptive controller so maybe that has something to do with it, even though it was off.  

 

Someone suggested uniting the grounds however that is on a fixed setup where you're not planning to move the thing and that also assumes you have a single ground The Edladdin looks like it has a double ground system for the ColecoVision.

 

General troubleshooting guide says you work with as few things as possible necessary and add them to see where the issue is which makes good troubleshooting sense.

 

I don't understand dual ground systems Heck I don't even understand the concept of a ground.  People on fighting game websites say it doesn't matter which side is the ground and which side is the signal.  Unfortunately I have a feeling that with this Colecovision system it does matter because these are called returns and these returns are separated into two paths or classes of returns. 

 

Anyone got some advice electrically about this? 

 

I know you're supposed to use the normally open side of the plugs in the actuator.
