This is the Sonic Community Hacking Guide for Sonic 3 & Knuckles. As Sonic 3 & Knuckles is a "lock-on" game, all offsets below $200000 are in the base Sonic & Knuckles ROM, and all offsets above $200000 are in the connected Sonic the Hedgehog 3 ROM. Since Sonic 3 & Knuckles runs on Sonic & Knuckles' engine, all the information on this page also applies to Sonic & Knuckles alone, with the exception of any pointers above $200000 (which are part of the locked-on Sonic 3 ROM).
