Supervision
Console Information

There are two basic shapes of the Supervision. One
is just like the shape of a GameBoy
and the other has a bendable mid-section. From these two basic shapes
came further variations
in colour, style and overall appearance.
Supervision originated from Hong Kong to compete with Japan's Nintendo
GameBoy in 1992. It has all the same parts in the same positions,
however, the Supervision benefits from a larger LCD screen and resolution
(160 x 160 pixels compared to GameBoy's 160 x 140 pixels; a negligible
difference) and the more prominent versions have a bendable mid-section
to adjust the screen's angle thus improving player comfort. The
A and B buttons are 50% larger than those on the GameBoy and there
is an extra sound channel. It has a headphones jack, DC jack, 2-player
link-up and the same button set-up as the GameBoy. It also has similar
games, but unfortunately the games were not as fun and challenging
as the GameBoy and so only about 65 were released in North America
with others distributed exclusively in other parts of the world.
The console itself, however, did have a fairly large following in
Europe and Asia, but not so much in other parts of the world. It
was because of the lack of quality games and not enough advertising
that the console did not survive.
The games were mostly in-house productions and not of a high standard,
however there were some games made by other companies like Bon Treasure,
GTC and Sachen.
The games sold for less than half the price of GameBoy games. The
console itself with a game, batteries and earphones was 5% cheaper
than a GameBoy with batteries only. Neither GameBoy or Supervision
games are compatible with each other nor is the 2-player link-up,
however the DC power supply for GameBoy can be used with the Supervision.
The Supervision has an extra stereo output channel for Audio DMA
on top of the four tonal and one noise channels that it and the
GameBoy have in common. Both of these consoles use VLSI processors
and 8-bit Microprocessor unit video chips.
The Supervision was licensed in many countries under different
labels. The companies often gave their own touch to the console
design which they manufactured (see more in the variations
section). Crystball
was the pack-in game with most versions of the Supervision, but
among one of the many Watara releases came one with Classic
Casino as the pack-in game. Supervision had a number of accessories
available to enhance the console.
It's a shame this console did not take off very well. It still
had a reasonable following, but not enough to keep it going. It
had potential and if it had lived as long as Nintendo's GameBoy,
we may have seen a colour version and one with improved graphics
too. The final Supervisions were made in 1996.
