Speedrunning is a particularly neat part of gaming culture, in which extremely dedicated and skilful players push games and their coding to the limit. Often exploiting glitches and - in the case of retro games - memory limitations of the original hardware, gamers find clever way to beat classic titles in a matter of minutes.
Super Mario World is a title that's often tackled in speedruns, with methods found to clear it in well under 10 minutes. Achieving this is extremely tricky, so the latest video from the A+Start channel on YouTube is well worth a watch. Though this run is over 40 seconds off the world record in its category - there are some quicker categories - there's some nice commentary that explains what's happening.
Check it out and let us know what you think, while this run from SethBling shows another - quicker - category, too.
