sega-cd-formatIn order to format the Backup RAM Cart, you must load a game into the Sega CD. On the power-up screen, press the C button to access the system menu as seen below. The menu screenshots shown to the right are representative of the North American Model 2 Sega CD. On a Model 1 Sega CD select “OPTION” instead of “MEMORY”. Note that the “MEMORY” option will not be available if no game is loaded into the Sega CD. Follow the on-screen instructions to format the Backup RAM Cart. From here, you may also copy save files to and from the Backup RAM Cart.
