On Romhack Thursdays, we bring you interesting finds from the world of game modifications.

This is a mostly silly hack by Daizo Dee Von, a winner in SMW Central’s Questionable Level Design Contest for 2025, that replaces Mario in Super Mario World with a mobile version of one of the Switch Palace switches, but it does have some interesting gameplay.

The player can switch their switch themselves by pressing L and R, but only by pressing in, not out. Doing so both changes the state of all the switch blocks, and makes the switch itself much shorter. In play terms, this is equivalent of Super Mario shinking and becoming Regular Mario, and in fact getting hit by an enemy has the same effect, resulting in being switched prematurely, and all the blocks changing state too. To switch back, you collect a P Switch item, which is essentially a Super Mushroom, restoring both the player’s state and reswitching all the blocks.

It’s a short hack, but it has secret areas and endings! They’re all shown off in Flook611’s playthrough and exploration of You Are Just A Blue Switch, here (18 minutes):

Or, you could just watch Daizo Dee Von’s own trailer for the hack (30 seconds):
