Sonic 2 Hacking Guide
From Sonic Retro
Sonic 2 Hacking Guide was the name given to the first Sonic the Hedgehog 2 hacking documentation released to the internet. It was written by Saxman and released in late December, 1998. It was directly inspired by information released by Tom Sonic detailing how to access Hidden Palace Zone through savestate modifications. It was last updated in 2004.
