I've finally finished a custom arcade stick I've made,

If these consoles you are referring to are actual hardware, then it won't be very easy.

You would have to program each "box" with something like a Tensy that knows how to send the correct signal to the console port.

> Would using something like HDMI be a bad idea?

I want you to go over the list of these boards that you're going to hook up to this thing and ask yourself that question again.

I think you guys misunderstand my idea.

Each button on the arcade stick has two wires: "on", and ground. The ground is common throughout the entire stick. There's 4 directions on the stick, 8 buttons on the face, a "coin"/back button, and a start button. That means I have a maximum of 15 wires.

The PCB of console pads typically has a common ground. When you "pad hack" a PCB, you are soldering two wires onto each corresponding button on the PCB: "on", and ground. So if I have a Saturn controller, there's 4 directions, 6 face buttons, and a start button.

My arcade stick wires would pass through the DB15 (for example), into the DB15 port on the project box. Then these wires would run to the console controller PCB which were "pad hacked". The PCB already does all the signal processing, and the PCB also already has a cable coming out of it which goes to the console.

I already have this working on my finished arcade stick. The only difference is I'm adding a DB15 (or whatever) "middle man". I don't see why HDMI wouldn't work as well, or any other standard where there are at least 15 insulated copper wires.

My problem is that I want to find something more wieldy than DB15. DB15 would mean that I have a big, fat cable coming out the rear of my arcade stick. I also want to find something that won't easily be yanked out. CAT5 would be a good one, but there are only 8 signal wires and they are of a fairly small diameter.

You want to get yourself a PS360+ PCB, as it'll do most of the work for you. You just need to make console -> RJ45 leads to connect to each of the consoles you want.

Will be a lot less wiring for what you want.

Holy shit that's amazing. Thanks bro.

If PS4 is a major concern to you then check out the PCBs that Brook makes - they have been pretty good so far about releasing firmware updates every time Sony releases a patch that breaks 3rd party controllers. If you go to fighting game tournaments where they use PS4s then I don't think they will let you use a stick with 8min timeout. I don't think their PCBs support many older consoles though...

My main use will be PC (xinput), X360, PS2, original Xbox, Saturn, and Dreamcast. If I do get a PS4 eventually, I would be fine with getting another stick for it but that's far into the future.
