The Green Demon Challenge is a ROM Hack based on a popular Self-Imposed Challenge for Super Mario 64 that revolves around the 1-Up Mushroom. The aim of the challenge is to collect all 8 Red Coins and the corresponding Power Star in the game's worlds while avoiding a 1-up Mushroom that homes in on you (the titular "Green Demon"). The original challenge was rather popular in Japan for years after the game's release; said popularity spiked after the Game Grumps posted videos showcasing their attempt at it. Before long, it became the subject of a ROM Hack, most notably played by YouTuber and speedrunner SimpleFlips.

In normal gameplay, only nine of the worlds can spawn that particular type of 1-up in the same area as its Red Coins. The hack extends this to every single world by making two relatively simple (yet critical) changes to the base Super Mario 64 game:

1. A homing 1-up appears soon after Mario enters the stage.
2. Both it and every other 1-up now reduces Mario's health to 0 if he touches it.

The 1-up Mushroom is decently fast, outpacing Mario unless he's constantly running full tilt, and it can fly much more freely; the challenge lies in the player refining their movement and knowledge of the stage, as it requires complex and creative maneuvers in order to keep the Green Demon away from Mario. While the challenge the hack made for focuses on the Red Coin Stars, players can attempt this with every stage if they so choose.

The ROM hack can be found here.

Tropes used in Green Demon Challenge include:

• Ability Required to Proceed: The Wing Cap is required at bare minimum; the other two caps are not required outside of their stages (or even within them, though they could potentially make life easier). Several of the other Red Coin stars naturally require stars from other (usually previous) stages to unlock.
• Dead Character Walking: Mario's death animation won't start until he touches down on land or in water; this can be exploited in Wing Mario Over the Rainbow to maintain flight via cannons and even collect all eight Red Coins!
• Difficulty Spike: Doubling back is practically required in some of the more "linear" stages, and Bowser in the Fire Sea in particular forces you to dodge two of them!<note>Two of the Red Coins require Mario to climb up a pole that releases a tracking 1-Up when he's near the top, and you have to climb to that height to get in to the structure it extends from.
• Do Well, But Not Perfect: A significant amount of the challenge lies in keeping track of the Green Demon's location. Players who get too far away or assume it's stuck without double-checking may be in for a nasty surprise - there's plenty of cases where it seems stuck, only for the player to be nearby when the Demon clips through something...
• Game-Breaking Bug: Tiny-Huge Island's pipes have a tendency to cause a softlock during the transition, forcing a reset; it's all the more likely if the Green Demon is near it, or else catches you on the way in.
• Kaizo Trap: The mushroom can still catch Mario during his star-collecting animation.
  • Anti-Frustration Features: However, if this happens things will proceed as normal; the star still counts, and Mario losing a life only takes effect after the player chooses to continue the game from the subsequent menu.
• Meaningless Lives: Version 1.3 adds infinite lives.
  • The code used to "create" the Green Demon is altered to remove its ability to grant extra lives, which would be an aversion if not for the aforementioned update.
• Memetic Mutation: After SimpleFlips' playthrough, the Green Demon became one of many recurring memes within his community; Green Demon-style 1-Ups are a more common troll in some of the hacks he plays, and were one of the cheats available for viewers during one of his Crowd Control playthroughs of Super Mario 64.
  • SimpleFlips himself created a stage designed around the original challenge in Super Mario Maker 2 using the remarkably similar Zombie Shrooms.
• Names To Run Away From Really Fast: The titular Green Demon, in a literal sense.
• One-Hit Kill: All 1-Up Mushrooms become literal poison mushrooms that are lethal on contact.
• Poison Mushroom: Version 1.2 even retextures the 1-Ups to be purple like the Poison Mushrooms in other games..
• Super-Persistent Predator: The 1-Up Mushroom can and often will clip through walls and platforms to reach Mario, effectively turning it into one of these and earning its "Green Demon" name.
• Unwinnable: Dire, Dire Docks is considered to be unbeatable in this mode, as Mario starts the stage over the water, and the player cannot gain control and move quickly enough in order to swim away from the 1-Up Mushroom, though there have been claims to the contrary. This is much more definitely the case with The Secret Aquarium, which starts with Mario already in the water.
• Weaksauce Weakness: In some stages, it's possible to trap the mushroom using certain walls or platforms, allowing the player to collect the Red Coins at their leisure. This only works some of the time, though...
