Play Mario Mappy (Mappy Hack) Online

Game Overview

Mario Mappy (Mappy Hack) is a weird little NES romhack that mashes up Mario's platforming with Mappy's item-collecting chaos. You're basically running through these maze-like stages, grabbing coins while dodging enemies—except now it's all Mario sprites and sound effects.

At first, it feels familiar, like a stripped-down Mario game, but then you realize the movement is floatier, and the level layouts force you to backtrack more than you'd expect. The enemies respawn constantly, so you end up just weaving through them instead of fighting most of the time.

It's not bad, just... different. The mashup works better than you'd think, though the collision can be janky in spots. If you're into obscure NES hacks, Mario Mappy (Mappy Hack) is worth a look.
