Most videogames completed simultaneously with a single controller (100%)

In a video uploaded to YouTube on 9 September 2011, the gamer known as "agwawaf" completed 100% tool-assisted runs of Mega Man X, Mega Man X2 and Mega Man X3, playing each game at the same time using a single controller, which had been wired into three SNES emulators. The gamer achieved this in 43 minutes 51 seconds – an incredibly fast time in its own right. The record for a non-tool-assisted 100% speed-run of Mega Man X3, according to Speedrun.com, was 45 minutes 18 seconds, as of 5 July 2016.

"agwawaf" also holds the record for most videogames completed simultaneously with a single controller (any%) – he finished four titles simultaneously with the same controller: Super Mario Bros., Super Mario Bros. 3 and Super Mario Bros. 2 (USA and Japan versions).
