I'm confused. Did you really think somebody found a way to do real-time raytracing on a stock SNES? I saw the title and the first thing I thought is "It's not possible, so clearly they did some black magic fuckery to subvert the system's limitations". I wasn't disappointed either, because it's impressive what he managed to do. Maybe try not to take every title completely literally? And maybe try a little bit harder to appreciate people's creativity and hard work?
