I have my pi in an arcade cabinet, and the stick w buttons is kinda tough to play modern games, so mostly play arcade classics on it. Was thinking of buying another, but w dev mode on xbox, prob won't now.
It took a few days building, I use a pi5 w RetroPie frontend. Ipac2 for the stick/buttons controller board. Mousetrack ball is just a usb. 32" monitor. Fans, rgb, etc.
I keep chewing on an idea.... Like patched ROMs for difficult to emulate systems, like part of the emulation has already been done. Almost a half step between decompiling and native.
