The worst Sonic the Hedgehog romhack (featuring mario)

By Sonic_the_dutch_hedgehog

The following romhack is a joke hack so please do not take this too seriously.

This sonic the hedgehog romhack features mario instead of sonic, hard (and sometimes troll-ish) level design and music from other games. The hack itself is pretty basic but there is 1 secret level. There is also green hill act 3 which is pretty much a auto level

What mario can do:

  • roll into a ball
  • air roll (useful for a boss)
  • has no speedcap

The reason i call this "the worst hack" is because of some things:

  1. the level design can be a little troll-ish
  2. mario cant spindash
  3. the goomba (motobug) badnik is way to fast
  4. you only get 1 life.

In the hack (not)green hill-final are there however certain zones arent:

  • Labyrinth act 3 (was removed because it somehow had the progress was removed)
  • Star Light act 2 (an error happend thats all)
  • Scrap Brain act 2-3 (With act 2 it was just i did not want to make another painful stage and act 3 is Labyrinth act 4)

Level select and debug are just the sonic 1 codes. There are some secrets in this hack so be for the lookout for them, good luck!



  • Hack made by me
  • Some smps tracks and ideas by pikanoob
  • assets taken from Sonic games (and high seas havoc)
  • Music from other megadrive games (Wiz 'n' Liz, Yu Yu Hakusho Makyou Touitsusen, outrunners, high seas havoc, Ristar, shinobi 3 and puyo puyo)

This ROM hack is that good that Mario doesn't need any frame animations. He's just using 1 frame for everything!
