This is based off a [tutorial](https://kbin.social/m/retroid/t/61253/How-to-set-up-dual-analog-controls-for-Perfect-Dark-and) I made for Mupen64 Plus on an Android based handheld, but since I got a steam deck, I wanted to get it working in Retroarch as well....
I apologize if this comes out weird, I've never crossposted from Kbin before. I hope it works.
Edit: It didn't. Link to the tutorial is in the title, sorry!
Edit 2: Maybe it did!
