I just found this the other day, and it's pretty difficult. It seems that emulators don't like it, since I tried to get it to work and it wouldn't on Kega. Ocean Resort would start, then the game would bug out a bit and restart. Here's the link to it that I found that works somewhat well. https://www.ssega.com/play/sonic-3-knuckles-hack-by-jukedenton-039/3904 It's the only reliable spot I've found. But can someone log this in the Sonic 3 and Knuckles hacks section, please?
