Professional speedrunner Bubzia dominated the blindfolded Super Mario 64 scene for years, aiming to beat his own record. However, a broken webcam invalidated his run just as he was on pace to set a new record. The community initially hoped for a new world record, but was ultimately disappointed by the glitch that rendered his efforts pointless. Bubzia expressed frustration after realizing his camera was off, but still managed to reach near-world-record pace despite mistakes in the endgame.
