Before the existence of Blue Retro or any commerically available adapter, I wanted to use Playstation 4 Dual Shock wireless controllers with my Sega Saturn as an analog controller. I used the Arduino USB Shield Adapter since that supported wireless Dual Shock controller and all I needed to handle was the Saturn side of things with emulating a controller protocol so the Saturn things it had a 3D controller plugged into it.

This was my introduction to Arduino programming, bitmasks and direct port manipulation. I have changed the recently to not use direct port manipulation since it really isn't need for the Saturn and I wanted to make the code more portable.

I have since made a wireless for the official 3D controllers for the Saturn with no noticeable latency. Something it seems is still taking others a while to figure out it. I am not doing anything fancy so I don't know how they can't figure that out yet. They are using Blue Retro though where as I am just using an nRF24L01. So maybe the Blue Retro is adding some unnecessary over head. This i have not released the source for though.
