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.

The VMU is normally powered by two CR2032 batteries which can drained after only a couple hours of use. Because the VMU requires a voltage of 6VDC, one can be modified to be powered by 4 AAA or AA batteries or a suitable AC adapter. See the VMU power supply mod page for a guide on how to do this simple mod yourself.
