Background

Control is through a single multi-position joystick and two sets of four buttons, one on each side of the joystick, for ease of play by both left- and right-handed players.

Rather than using an LCD screen or an external television set like other systems of the time, the Adventure Vision uses a single vertical line of 40 red LEDs combined with a spinning mirror inside the casing. This allows for a screen resolution of 150 × 40 pixels. Another product using this technique was produced by Nintendo in the mid 1990s–the Virtual Boy.

The game cartridges can be stored in spaces on top of the case.

Drawbacks to the Adventure Vision are its monochrome (red) screen as well as the mirror motor, which draws a great deal of power from the batteries. The latter problem can be avoided by the use of the built-in AC adapter port.

Entex released four games for the Adventure Vision:

On March 31, 2013 at the Revision demoparty, the first ever homebrew/demo ROM for the system was demonstrated[2] by MEGA - Museum of Electronic Games & Art; a video can be seen at http://www.youtube.com/watch?v=1q-4Ie5wjus MEGA also released[3] the source code for the demo as well as all development tools.
