Sonic the Hedgehog: Editable ROM

On March 13th, 2022, @Kaua16 and @CloudyCrack555Gamer posted a ROM hack to GameJolt^[2] based on Sonic.EYX and a creepypasta version of Tails, Cynffonnau, titled, "Sonic the Hedgehog: Editable ROM." The game is presented as a cursed ROM hack controlled by Sonic.EYX. It plays like a normal Sonic game at first where the player takes control of Tails. Once Tails encounters Sonic, the game begins to glitch as Sonic.EYX manipulates it. The game crashes a number of times by design and becomes further manipulated with each launch.
