For those unaware, Bad Apple!! is the name of a song from Lotus Land Story (Touhou Gensoukyou). More famously, it's the name of a video featuring several Touhou girls in silhouette, alongside a remix of the original song (with vocals by "Nomico"), first posted onto NicoNicoDouga years ago. More relevantly, it's become an unwritten challenge to port that video to any and every computer, display, game system, processor, and architecture. And that's where we'll start.
