Allan Cecil, a speedrunner and hacker, is trying to debunk the world’s fastest video game speedrun

Allan Cecil plans to present evidence that a speedrunning record for the 1996 PC game Diablo was in fact the result of rule-breaking techniques.

Cecil says he arrived at his fixation with catching cheaters in part out of a determination to protect this lesser-known field of speedrunning from those who would surreptitiously use the same tools in deceptive ways.

Cecil maintains that tool-assisted speedruns, in which players meticulously rewind, replay, hone and perfect their runs frame by frame, can be its own valid form of competition.

Maselewski 's 3-minute-12-second Diablo speedrun time was 3 minutes and 12 seconds .

Cecil and his team of investigators found evidence of possible tampering in the video.

Cecil says the team found a long list of inconsistencies in software, missing frames, and other signs of potential tampering.

The Guinness Book of World Records has declined to comment on whether it will take down Maseleski 's record.

Tim Cecil is trying to debunk the Diablo Diablo speedrunner's alleged cheating record.

He says a tool-assisted speedrun on a real Atari 2600 would show Rogers' record was impossible.

Cecil says he hopes his work will help keep speedrunners honest and fuel the tools they've helped pioneer.
