SCHG How-to:Guide

The SCHG How-to: series is a spinoff from the Sonic Community Hacking Guide with a focus on how-to, tutorials, and supplementary education. Whereas the traditional SCHG serves more as a map for users to navigate a ROM for themselves, the How-to series is more a "how to get from point A to point B" set of directions. Tutorials range from the very basic to very complex, with an eye towards making sure no part of the process is assumed or left out.
