Arguably better known these days for the WarioWare series, our anti-hero Wario started off as the villain in Super Mario Land 2 before starring in his own series of platformers of which this is the fifth (everyone forgets Virtual Boy Wario Land).
Through strategic use of save-and-restore and a glitch allowing rapid diagonal movement and zipping, Wario gets away with all the loot in this normal mode run by Reseren, which features different routing compared to Hard mode.
Watch a resync of this run being played back on a real console.
