@Tfmonkey I reckon you can have one of those be an emulation arcade in order to emulate games you may not have on the other ones or to emulate arcade like games that were never put on arcades. But either ways it’s kinda insane you can just use a steam deck to do just emulate everything and do it well.
@Tfmonkey custom arcade a guy made. Thought this might interest you. https://youtu.be/mLPtyrNHmlo
