Super Mario (NES) Speed Run Record

How the hell do you do this?!!!

Well damn I was impressed when my mate Tim Clark, did Sonic the Hedgehog: Green Hill Zone: Act

 1 in 23 seconds!

Beating my best of 24, the bastard!

It was a running challenge for about a week at work, since we had a Mega Drive/ Genesis hooked up in the staff room!

So is this an epic achievement unlocked? Or a fake?

The YouTube community are divided on this record!
