DaemonBite-Retro-Controllers-USB

Not sure if this has been mentioned already: https://github.com/MickGyver/DaemonBite-Retro-Controllers-US... It's how to build your own demon bite adapters using Arduino, for various console. These are super low lag. If you Google demon bite you can find various sites selling premade adapters. These are really popular with mister fpga users: https://en.m.wikipedia.org/wiki/MiSTer This is a bit of a rabbit hole, the mister is the best retro related thing I've bought / built. Here's a useful listing of various usb adapters and their latency: https://rpubs.com/misteraddons/inputlatency

The Daemonbite project (https://github.com/MickGyver/DaemonBite-Retro-Controllers-US...) does essentially the same thing, but works like a normal USB controller from the perspective of the host. I've used one with a MiSTer FPGA setup and it's almost indistinguishable from a native SNES controller in terms of response. For my build, I cut a cheap controller extension cord in half, avoiding the need to actually modify the controller itself.
