Super Spooky Mario 666 [2019 Demo] is a ROM hack of Super Mario 64 for the Nintendo 64, released in 2019. It's likely a horror-themed modification, suggested by its title.  The original Super Mario 64 gameplay focused on exploration and platforming. This ROM hack, however, appears to reimagine the familiar environments and potentially characters in a darker, spookier context. The 2019 release date indicates a more recent creation, showcasing ongoing fan activity in the Nintendo 64 ROM hacking scene. The developer is likely a member of the ROM hacking community and distributed the game informally.
