Visual Memory Unit (VMU) Technical Specification
- CPU: 8-bit
- Memory: 128 KB
- Display: 48 dot (W) x 32 dot (H) Monochrome
- Display size: 37 mm (W) x 26 mm (H)
- Case dimensions: 47 mm (W) x 80 mm (H) x 16 mm (D)
- Power source: 2 x button batteries, w. auto-off function (at least two technical variations exist; VMUs manufactured until sometime after the North American launch used their internal battery power while they were inserted into a controller port while the Dreamcast was on; this led to very short VMU battery lifespan. This continued through at least the initial North American release of the yellow VMUs, but was corrected by the North American launch of the red, green, and black VMUs).
- Sound: 1-channel PWM sound source
- Weight: 45g
Trivia
- The Dreamcast sold 101,490 units in its first weekend after launch in Japan. It was the first 128-bit console and the first console capable of a worldwide internet connection. It also featured the first cel-shaded videogames, Wacky Races and Jet Set Radio.
- The last commercial game released for the Dreamcast was released in early 2006 and was a scrolling shooter.
