Thin Chen Enterprise (full name Sheng Qian Enterprise Co., Ltd (Chinese: 聖謙企業股份有限公司)), also known as Sachen, was a Taiwanese company that developed several original games for the Nintendo Entertainment System, Mega Drive, Game Boy and other early cartridge-based handheld systems such as the Watara Supervision and Mega Duck.
With the exception of the latter two handhelds, all of Thin Chen's games were produced without license from the console manufacturers.
[2] Many of its games were released in an unfinished state, and received largely negative critical response.
Several of their NES games were released outside Taiwan under license by foreign publishers, including: HES Interactive in Australia, Hacker International in Japan (usually with added pornographic content), Bunch Games/Color Dreams and American Video Entertainment in the United States, and Milmar in Brazil.
[1] Note: All series of Super Cartridge Version, was developed and released as Thin Chen Enterprise.
