A “new” prototype of the game Punch-Out!! on NES was been found and archived. It’s one of the most unique prototypes found ever given its a game from Nintendo. There are placeholder stuff everywhere, its unfinished and has no audio. Playable on any NES / Famicom emulator.

Important note: Rename the Rom to “Punch-Out!! (Proto).nes”, the way No-Intro group does. Why? Because not following that naming scheme is a crime. (Just a joke, do whatever you want.)
