A legendary Diablo speedrun from 2009, long considered unbeatable, has been proven fraudulent through rigorous investigation. A team of speedrunners used custom tools to analyze the game's code and map generation. Their analysis revealed inconsistencies suggesting the run was spliced together from multiple attempts and modified. The findings prompted Speed Demos Archive to remove all of Groobo's Diablo runs. The revelation has reignited interest in Diablo speedrunning after a period of stagnation caused by the seemingly impossible record.
