This is a linux computer where the terminal is the primary intended interface. Anything you can run on ARM and linux (like everything in retropie) should be supported out of the box. Terminal-based games don't need fancy GPU drivers and optimizations like the Steam Deck. There should be no porting needed except maybe some keymapping for the non-keyboard buttons, but that's normal.
