This page will contain a list of guides for you to apply any of the various permanent mods to your disassembly of Sonic 1. Unlike elective mods which are toggleable, and relatively simplistic in nature, these mods are usually more complex and require both a greater amount of explanation, as well as a greater amount of skill and understanding by the user to apply to their own disassembly. Due to this, such guides will take a greater amount of time to complete. In some cases, I'll instead opt to link you to an installation guide provided by the original author(s).
