Play Circus Mario (Circus Charlie Hack) Online

Game Overview

Circus Mario (Circus Charlie Hack) is a weird little NES rom hack that turns the classic arcade game into a Mario-themed sideshow. You jump through flaming hoops, bounce on trampolines, and ride unicycles—except now it's all with Mario sprites awkwardly pasted over the original animations.

The controls feel stiff, like you're fighting the physics the whole time. Miss a jump, and you'll watch Mario faceplant into the sawdust while the timer ticks down. It's janky, but there's something oddly charming about seeing him struggle through these circus stunts.

Don't expect polish—some sprites flicker, and the collision detection is rough. But if you're into oddball retro hacks, Circus Mario (Circus Charlie Hack) has a weird appeal.
