Monsters, Inc. is a very basic ROM hack of the Japanese version of Wacky Races (Chiki Chiki Machine Mou Race) by Atlus. The game can be found in a 4-in-1 cartridge, and was released as a standalone cartridge (confirmation needed).


There are several changes from original game:

  • Muttley is now a pink Sulley, and Dick Dastardly is now Mike Wazowski. Both still appearing on title screen without changes.
  • A few of the sprites were altered, such as the extra life icon.
  • The background color of the title screen was changed from a darker red to a purple-ish blue.
  • All copyright info has been removed from the game; standard practice for bootleg hacks.



  • The title screen has the letter S in "Monster" has Shrek's ears on it.
