With any gaming console that uses CD's as opposed to cartridges, external data storage is a neccessity. The first stand-alone console to use CD's, the Sega Saturn, had internal memory, but the popular Playstation used small memory cards instead. Sega one-upped this idea on thier Dreamcast with the Visual Memory Unit (VMU).

As with other memory cards, the VMU stores saved game information from your favorite games. However, unlike other cards, the VMU has a tiny (about 1"x1") screen included that serves a variety of purposes.

In certain games, the VMU relays information to the player. In sports games, for example, the VMU displays information for picking plays, so that it's not displayed on the screen for other players to see. Often, the VMU notes when the game is loading or when certain special events occur. This tiny screen really comes in handy in some games where you'd rather not have certain info cluttering up the screen.

On it's own, you can use this screen to work with the data on the VMU. You can copy, trade, and delete files without having to use the console. Two VMU's can link up so you can easily trade data with friends.

Also, some games have mini-games that can be downloaded to the VMU. It then plays like a small handheld game, and often the mini-games have effects in the normal game when you 'beat' them. This greatly expands the depth and enjoyment of games with this feature.

With the VMU, Sega has created an almost perfect addition to a great console. The VMU is easy to use and durable. I left mine in my car overnight when temperatures dropped well below freezing, and I was afraid that the screen would have cracked, but it was fully intact. The only downside is that the VMU eats up batteries very very quickly. Fortunately, the #3032 batteries it takes are inexpensive, and you can easily minimize the battery wear by paying attention to using the VMU by itself only when needed.

Overall, a great product, and though it's a neccesity for the Dreamcast, I'd buy a few even if they weren't!
