A nearly forgotten entry in the portable gaming market, the Supervision was released in the U.S. in 1992 as a low-cost competitor to Nintendo's Game Boy. Developed and manufactured by Hong Kong's Watara Industries, the Supervision has specs comparable to the Game Boy, with an 8-bit CPU, monochrome screen, stereo sound and two-player link capabilities. The system actually improves on the Game Boy in a few areas, such as a larger screen size (3.3" vs. 2.6"), a slightly higher screen resolution, an additional sound channel, and the ability to adjust the viewing angle of the display.
The $49.95 Supervision came bundled with the Breakout-style game Crystball, four "AA" batteries, and a set of earphones. Surprisingly, over 60 games were released in the U.S., with prices ranging between $8.95 and $14.95. The one peripheral for the system was an add-on called the "TV Link" that allowed players to play Supervision games on their television. ~ Skyler Miller, All Game Guide
