Purveyors of video game secrets have something new to get excited about following the recent fuss around Nier: Automata’s ultimately rather underwhelming church mystery; a hidden two-player mode has been uncovered in Super Punch-Out!!, 28 years after its release on the SNES.

As explained by Unlisted Cheats – a Twitter account specialising in video game “secrets nobody heard about until now” – the discovery was made “while doing some request work” on Super Punch-Out and has revealed two additional cheat codes on top of the sound test and Japanese name input cheats previously known.

The first cheat unlocks a stage select screen enabling players to take on any fighter, including Special Circuit fighters, in a free single match. This can be accessed from Super Punch-Out’s title screen by holding down Y and R on Controller 2 and then hitting A or Start on Controller 1.

Get the first step right and you’ll be taken to this character select screen.

Things get even niftier, however, when you select one of the fighters on this newly revealed screen then, from their details page, hold down Controller 2’s B and Y buttons and hit A or Start on Controller 1. This makes it possible for a human player to take control of the ordinarily CPU-driven opponent character using the second controller for a spot of two-player fun.
