It definitely would be! I like the idea of a portable with a dock that works like a Switch one (ie. charging, video, and gamecube controllers, over one port) but don't know if that's feasible.
I've wanted to build a portable ever since I saw this one years ago. Do you have any information you can share on how you got the controller ports and AV out working? I love the idea of docking one of these to a CRT. Thank you!
