The articles I read assume you just want to emulate a game using RetroPI. I want to create a Unity game that runs as arcade cabinet, hopefully that distinction makes sense. I suppose I could read the sourcecode of RetroPI and see how they configure linux to run RetroPI. That seems applicable. Alternatively, I guess I can see if I can export my game for one of the supported RetroPI systems...?
