kronos's Introduction

[

Sega Saturn Emulated Hardware

You can read about the Sega Saturn Console and is components here.

Building

CMake

The CMake system has been refined to build the full Yabause stack. you have to download CMake and run it in the root of the first CMakeLists.txt. Currently in /yabause/CMakeLists.txt.

Platforms

Since CMake is a true cross platform build tool you can build on plenty of platforms and easily add new ones.

Currently used are:

Windows
Linux (Debian)

QT Version

You can set the CMake flag YAB_USE_QT5 to build a Standalone version which requires you to have QT5 installed

LibRetro - RetroArch Version

For this you need to se the CMake flag KRONOS_LIBRETRO_CORE. This will build a version of the core consuming LibRetro and there fore can be used with LibRetro compatible front-ends like RetroArch (which is what i test against)

Old make build script (obsolete)

The old build script is still there for reference. It contains custom build code for various platforms and is the base reference for newer entries in the CMake code. It is still though considered obsolete.

For retroarch core:

mkdir build_retro; cd build_retro;
make -j4 -C ../yabause/src/libretro/ generate-files
make -j4 -C ../yabause/src/libretro/
then execute retroarch -L ../yabause/src/libretro/kronos_libretro.so path_to_your_iso

Pre-Build Versions

Older Builds

Older Windows builds can be found here!

Platform Notes

RetroArch

Is the Frontend which is used for manual tests

Windows

Works quite well on a modern Hardware.

Raspberry Pi 4 Raspberian OS

Has currently various problems running and is not usable.

The Shaders are too complex and Mesa can not handle that. It will fail with a driver crash with Mesa 19.2
Code is to demanding on the CPU by now even with frameskip 5 there is no acceptable framerate even on 2d games.
