Firmware and menu

There are two bits of software which make the Satiator run: the firmware and the menu.

The firmware is flashed to the Satiator itself. The firmware is where the magic happens - hooking itself into the Saturn's CD block, emulating discs, et cetera. New firmware is loaded by putting a satiator.fw on your SD card; see the instructions below for more detail.

The menu is stored on the SD card, in the file menu.bin. The menu is the code that runs on the Saturn to list all your games and so forth. There's no special procedure to update the menu - just drop the new menu.bin on to your card.


Firmware releases are found here.

Firmware is updated by loading a new satiator.fw on to your SD card, and then powering on the Satiator, either via USB or turning on your Saturn. You should then wait until the LED displays three green blinks, indicating that flashing has completed. Then, you can cycle power again to boot into the new firmware.

If you interrupt power while it's still flashing the new firmware, you can get stuck with the LED showing a different blink code (red red green). If this happens, check out the troubleshooting instructions for an interrupted firmware update.

Official menu releases are found here.

The menu is updated just by dropping a new menu.bin on to your SD card. The Satiator reads it fresh on every boot, so there's no special flashing procedure required.

The menu is open source; the source code currently lives on GitHub.

This means people can also make other, more awesome menus for the Satiator. These add support for cover art, save game management, and various other features! This includes Satiator Menu Kai, which is distributed as part of Pseudo Saturn Kai. There is also the Rings menu, which is not currently under active development.
