Produced by the Hong Kong-based Welback Holdings, the oddly-named Mega Duck was marketed under a number of companies throughout the world, like Creatronic, Videojet and Cougar USA (hence the redubbing in the US as the Cougar Boy). Welback positioned it as a "rival" to the Game Boy.
The electronics inside the system are oddly similar to those of the Watara Supervision - the positioning of certain components is virtually identical! - with the exception of less cartridge pins and a bigger screen.
Most of the games were produced by Taiwanese company Thin Chen Enterprise, better known as the infamous unlicensed developers Sachen, and they would mostly go on to be ported to the Game Boy as part of multicarts.
