A Sega Saturn emulator.
erings is a work in progress. Pretty much all of the console's major internal hardware components are implemented to some extent. Many games run and a number of them at full speed. However, there are still plenty bugs to find.
The focus of erings is to play the majority of officially licensed games while focusing on the user experience. This is not intended to be a perfect emulator of every aspect of the Saturn. Some features and components are purposely not supported and never will be. It might be better to think of this as a Saturn game player than a digital Saturn console.
This is a gaming first emulator and not intended as game development tool. You won't find an integrated debugger you can step through. You won't find any kind of editor. The only development tools are intended for helping debug the emulator itself.
What you will find is a clean UI allowing you organize and play games. With a controller first navigation system. Make erings full screen, sit back and have fun playing some amazing classic games.

- Runs through the eblitui desktop UI
- RetroAchievements
- NTSC and PAL region
- A 4MB extended RAM cartridge
- Single player digital controller only (the core supports a second controller, but the UI does not)
- Internal backup RAM (console saves) persists between sessions
- Save states
- MPEG card
BIOS region patching is supported. Meaning you can use a US BIOS to play Japanese games or a Japanese BIOS to play US games. Or just use the HLE BIOS and not worry about it.
Several disc image formats are supported
- chd
- cue (tracks must have .bin extension)
A Saturn BIOS image (USA or Japan) is optional. Without one, a built-in HLE (high-level emulation) BIOS boots the game. A real BIOS is not included with the emulator and needs to be user sourced.
Build the desktop binary with make: make. This provides a binary that
can be run locally on the command line. This produces a debug build.
Release builds are created when building OS packages.
Proper OS specific packages can be built using make targets.
windowsmacosappimage
All builds are put into the ./build directory.
Game controls (D-pad, buttons) are configured in the UI's input settings.
