EvilEngine/SDF (File Format)

Introduction

SDF files are most likely the original level files that the developers at Heavy Iron worked with in their level editor tool, before compiling them into HIP/HOP archives that the game can read.

Instead of two individual HIP and HOP archives, all of the assets are contained in one SDF file. The main difference from HIP/HOP is that SDF files only reference external files by path (models, textures, sounds, text files, etc.). In order to view those assets in a SDF editor, you would need those external files someplace else on your computer. In our case, we don't already have these external files, but since they are included in HIP/HOP archives, we can simply extract them and use them as external files.

SDF files are only present on the GameCube version of Scooby-Doo and BFBB, and are ignored by the game.

General Info

SDF files are little endian.
