Scykoh‘s Glitchfest series is all about breaking popular games in as many ways as possible. TASVideos’s resources for NES Mega Man games covers several methods for moving through the game quickly, but even that doesn’t explain what Scykoh does in Ice Man’s stage. When I planned the “bugs” in Skeleton Hunter, the first place I looked for inspiration was Mega Man 1’s zipping, pause tricks, and tileset corruption, and they’re shown off very well here.
