The Fenrir is an ODE (Optical Drive Emulator) created by Ced2911 that allows you to emulate your Saturn's optical disc drive and run Saturn games without using the disc. While it was originally intended to physically replace the disc drive, a separate mod — the Saturn:Saturn Switcher — allows you to have both the ODE and disc drive installed at the same time.
