Resources

Resources are the data files that contain things like 3D models, textures, animations and any other kind of assets. Many of these resources are stored in proprietary formats optimized for fast loading times, and thus require special tools to be edited by modders. Many of them are also built using proprietary SEGA technologies, like the ASM animation system. On this page we provide a list of all known resources supported by the Hedgehog Engine, their support in various games and tools that can be used to edit them.

Archives

Archives are compressed archives ("zip files") that contain most of the game's data.

Levels

Levels are a new system in Sonic Frontiers and up that allow the game to dynamically load other resources when they are needed. They specify which resources need to be loaded to load a certain "level". This is a system similar to Unreal Engine's level system.
