Hi folks. I joined after seeing this thread and thinking someone might be interested in a similar edit I'd been working on for my own purposes. Head to the Sonic 3 Complete (hack) wiki page to download the latest version and read about what it does. Since I'm putting this into the public domain, allow me to take a moment to credit shobiz, whose code to do the initial music switch stuff got me started on this project (found at SSRG), and apologies to the Megamix folks for making off with the B+C Super activation concept, which turned out to be just the solution to "NO KNUCKLES STOP TURNING HYPER" I'd wanted since I first played S3K (though it has partly been replaced again now). Plus about a squillion other contributors who've helped since this original post; they are now listed on the Wiki.
