The Video Display Controller of the Mega Duck/Cougar Boy has one special feature, the display logic uses two "display planes" that are used to create parallax scrolling backgrounds, as if the picture is drawn on two sheets of which the top sheet is partly transparent.[3][4]

The Mega Duck and Cougar Boy with identical games for both systems.

This is an (incomplete) list of Mega Duck/Cougar Boy games. Each Mega Duck/Cougar Boy game is similarly labeled as the same games were marketed for both systems, although not all games were released for the Cougar Boy. The notation MDxxx is used for Mega Duck Games, and the notation CBxxx for a Cougar Boy Games. A MD002 is exactly the same game as the CB002, even to a point that some "Cougar Boy" games start up with a Mega Duck logo. Some notation numbers go unused, going up to 037, but missing 012 and 023 for example.

With the exception of the pack-in game for the Mega Duck (The Brick Wall) which was developed by the manufacturer, all games were developed by Thin Chen Enterprise under the "Sachen" and "Commin" brand names, and were later re-released for the Game Boy in 4-in-1 and 8-in-1 cartridges without the licence from Nintendo.

Although 24 cartridges (not counting cougar boy variants or add-ons for the Super Junior Computer) are known to exist, another game is listed on various websites called Tip & Tap[5], however, it is not known if the game was ever released, or if it existed at all.

   Background shading indicates games that have a Cougar Boy Variant.
