A popular item these days are “mini docks” for the Nintendo Switch, where you transplant the internals of the Switch dock into a much smaller case. The mini docks are very compact, and they do not scratch the screen when docking the console.
I think it would be great if such a dock looked like the NES Game Genie, mostly because the extending bracket makes for a good easel. Does anyone else miss cheat codes? It used to be such a big deal in gaming.
