Adventure Vision is a cartridge-based video game console released by Entex Industries in either August or October 1982. The launch price of the system was $79.95.[2] The monitor, game controls, and computer hardware are all contained within a single portable unit. The LED monitor can only display red pixels. Four games were released, all of which are arcade ports. Either approximately 10,000[3][2] or 50,757[1][4] units were produced.

Adventure Vision was Entex's second-generation system following the Entex Select-A-Game, released a year earlier in 1981.

Description[edit]

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.[2] This allows for an effective screen resolution of 150 × 40 pixels.[2] The mirror motor draws a great deal of power from the batteries, which can be avoided by using the built-in AC adapter.[5]

Games[edit]

Entex released four Adventure Vision games, all of them ported from arcades:

Legacy[edit]

A similar display technique combining red LEDs with a moving mirror was used by Nintendo in the 1995 Virtual Boy.

Because of the moving parts used by the system, many units no longer work, with an estimated 100 known operational units left.[4]

On March 31, 2013 at the Revision demoparty, the first-ever homebrew/demo ROM for the system was demonstrated[8] by MEGA - Museum of Electronic Games & Art. MEGA also released[9] the source code for the demo as well as all development tools.

The system is supported by the MESS emulator and AdViEmulator.[10]
