The Saturn Homebrew Repository for Example Code, or SHREC, strives to provide working examples of code necessary to create homebrew games for the Sega Saturn using tools currently available for free online.
XL2 has created a set of tools for his Sonic Z-Treme and followup FPS projects. These tools are designed to cooperate with SGL and Jo Engine to expand functionality into 3D rendering along with optimized handling of other game assets, such as file system operations and sound playback.
