Sega Saturn SGL Graphics Tutorial examples

Repository including the examples of the SGL Developer's Manual Tutorial.pdf with a README.md personal explanation of every example.

This is a learning repository, but the idea is to be able someday to make my first homebrew game for Sega Saturn

Setup Development Environment

Clone the repository and open it, for example, with Visual Studio Code.

If you are familiar with the C / C++ extension then make sure you add the necessary compiler paths to it so you can get rid of the include errors you may in the .c files.

Check https://www.infochunk.com/saturn/vscode.html if needed

The current setup only works in Windows, please check the Work in Progress section.

Project Structure

Every project follows the same structure which has been copied from the repository mentioned in the Credits section. You can find the following files

• clean.bat: Cleans the C compile objects and the generated .cue and executable files for Sega Saturn

• compile.bat: Compiles the project and generates the executables such as the .cue which can be played in a Sega Saturn emulator or burn a CD to be run in the Sega Saturn hardware instead.

• Mednafen.bat: Ejecutes the generated .cue in the Mednafen emulator.

Also two folders are found:

• ZTE: Configures the workarea and setup many variables such as the maximum vertices or maximun polygons

• cd: Folder which needs to exist by the compiler setup in order to produce the cue file

The main.c is the game infinite loop.

Work in Progress

This setup is based in Jo Engine. You can find a more modern compilator structure for Windows / Linux at: https://github.com/johannes-fetz/joengine

I will re-factor the project to be easy to compile with Yaul Docker which is agnostic to Windows / Linux / MacOS.
