These builds are killer. I've made a few for family members an they completely lost their shit when they saw how seamless it all worked. Some use PS3 controllers, some used PS4 controllers, some use XBox controllers, some used weird Chinese USB knock off stuff, it all worked great. And some even over bluetooth. What blew my mind was how well the Pi 3 B+ runs PS1 games. I have so many old PS1 RPGs that I don't wanna take out of the cases anymore, so it was a complete god-send.
I didn't get all fancy with the small LCD screen, but yeah, I love this distro.
