I've always wanted to add usb controller functionality to an arcade cabinet. Recently I have been working on an astro city cabinet and have plans to wire in UD USB Screw Terminal Decoders into the harness to have a dual action control system. I'd like to keep the original Astro CP controls but add the ability to plug in your own stick for those that are very picky of the controls that they play on.
As I get closer to the project I'm left thinking I really don't know what would be best way to tap the controls.
Do I just splice the leads into the wiring at the button? At the jamma harness? at the AMP connectors on the control?
What do you guys think?
He tapped his decoder into the controls.
I made a AMP harness splitter. Comes out from the cab. One goes to original controls. And the other goes to the 20 pin or whatever connector on the UD board.
They both worked out just fine. Just depends on what you have the ability to do. Overall pretty easy.
