It was simple once I figured out what I needed, but I had to cycle through a few different OSes before I got something that worked with my hardware. You might have luck with a "specifically for emulation" build like Lakka or Batocera, but for me I wound up installing Debian 12 and then having it just auto-login and run RetroPie on start. Works great though.
Anywho, best of luck!
