Super Punch-Out!!! has a hidden two-player mode that was just discovered nearly three decades after the game’s original 1994 release (via Kotaku). If you want to mess around with it but don’t have an SNES hooked up, you can actually give the secret mode a shot on the version of the game currently available to Nintendo Switch Online subscribers.

The new two-player mode — and a fight select screen — were revealed by the Twitter account Unlisted Cheats in a thread on Monday. To activate them, you’ll need to have two controllers hooked up to your console of choice. (On Switch, I got them to work with a Pro Controller as player one and two Joy-Cons acting as one controller as player two.)

At the title, hold Y+R, then press A or START. Following screen will appear instead or regular menus. Here you can select any character to fight a free single match. See, even fighters from SPECIAL CIRCUIT are available here. -> pic.twitter.com/Hh7AtPdTcK

Next, you can activate the two-player mode. Highlight the fighter you or a friend might want to play as and then hold down B and Y at the same time on the player two controller, followed by A or Start on the player one controller. (I again used the plus button on my Pro Controller.) At the pre-fight screen, keep holding down B and Y on the player two controller and have player one press start to get through it.

The fight will start up, and the player two controller should be able to control the
