Thin Chen Enterprise (full name Sheng Qian Enterprise Co., Ltd ()), also known as Sachen, was a Taiwanese company that published 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. The company produced at least 70 unique games for the NES and Famicom and at least 32 for the Game Boy (compiled into eight 4-in-1 cartridges), making it the most prolific unlicensed publisher for both consoles. The company also produced its own Nintendo Entertainment System hardware clones, such as the Q-Boy. Many of its games were released in an unfinished state, and received largely negative critical response.
Most of Thin Chen's products were released under the "Sachen" brand name, although the name Commin was also used for games on handheld consoles. 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.
Their earlier games were developed by a branch called Joy Van, before it merged with Thin Chen and became its development team.
