So here you go. <a href=\"http://www.hacking-cult.org/?r/4\">The awesome Sonic 2 guide by StephenUK and SHB</a>. 

On a small note, I uploaded the S2 Rev00 disassembly as well as the differences between Rev00 and Rev01.

Btw, there will be a v1.1 of Tails in Sonic 1. With fixed flying, tails and more!
