How to Set Up an SD Card with Rmenu for Rhea / Phoebe Sega Saturn ODE

Rhea and Phoebe are Optical Drive Emulators for the Sega Saturn. They replace the optical disc drive with an SD Card reader which allows the loading of game images. Rhea and Phoebe do not come with a menu to load games, instead the devices rely on a button which when pressed cycles through the games one by one. Luckily a menu was created by a third party to allow a more straight forward way of selecting a game image. This guide will show how to set up an SD Card with game images and install the RMenu interface.
