This is the Sonic Community Hacking Guide for Sonic Heroes.

Most of the information in this guide applies only to the PC version, although some of it can be applied to the console vesions as well.
This page is for information that does not fit into another page and does not warrant its own page.


This is an in-depth, technical overview of mostly documentation regarding various file formats used throughout the game, intended to be useful to actual hackers and programmers.

If you are interested in modding the game using pre-existing tools, consider checking out this tutorial on GameBanana. Also, here you can find an updated level editing tutorial.

If you are an end user, looking to simply play some mods, consider visiting this guide.
