The <b>VMU</b>, or <b>Visual Memory Unit</b>, is an accessory for the [[Sega Dreamcast]] which functions primarily as a storage device for save files. During gameplay, a VMU attached to a controller may display additional helpful information for the game or just the game's logo. The VMU can be used independently of the Dreamcast to manage save data or play mini-games downloaded from full Dreamcast games.
