NOTE THE BLUE SEGA VIRTUAL MEMORY UNIT IS NTSC AND NOT PAL BUT IT FULLY WORKS WITH THE PAL EQUIPMENT
The offical sega dreamcast virtual memory unit is essential for anyone with a sega dreamcast.
This is more than just a standard game saving memory card ,it is complete with it's own LCD screen and controller buttons ,it displays writing or game pictures depending on the game you're playing ,the virtual memory unit (VMU) can...
Play self-contained VMU games
Display secret info during dreamcast gameplay (i like seeing the health meter on the LCD screen when playing resident evil 3)
Download and modify characters from dreamcast games
Trade files with other VMUs
Save dreamcast game files
Unfortunately it uses 2 CR2032 batteries like used in the sega saturns console memory which only uses 1 and they can deplete very quickly depending on how you use the vmu ,the batteries will last about 7 days of continuous use when playing games and when playing against other vmu's or saving data and copying files frequently it uses up the batteries quicker ,it's only a minor downfall to this memory unit because you can still save game data even though the batteries are flat ,you only need the batteries for linking up or playing a vmu mini game.
