Since all my of my consoles now outputs s-video I decided to build my favourite supergun s-video encoder pcb into my supergun. For those who aren't familiar an arcade supergun is a device that lets you play arcade machine circuit boards on a regular tv and controller. Here's the s-video jack:
Here's what the inside looks like:
There's actually another pcb you can't see in this picture because it's completely buried underneath wires. The buried pcb is the rgb to s-video encoder. It also outputs composite video but the composite video looks terrible so I didn't wire up composite. Luckily the s-video looks perfect.
And for anyone interested here's what the supergun looks like when it's all put together
The usb cables coming out of it connect to the pcb for games that use more than 3 buttons.
