You may very well remember an old issue of GamePro that featured a 2-page article that completely debunked SEGA's talk of 'blast processing' on the Genesis. Back in the day, SEGA pushed blast processing as the reason why Sonic was so fast, and that the SNES didn't have blast processing.
Well, the article above puts all that talk to bed, and explains why blast processing isn't real, and how the SNES could handle anything that the Genesis could. The most interesting part about this article? It's actually a two-page advertisement, and not a magazine feature! I think it's obvious that the Big N was behind this feature, but I'd love to know how much they paid for it!
