Most of Thin Chen's products were released under the 'Sachen' brand name, although the names Joy Van and Commin were also used for certain early games for the Famicom and handheld consoles respectively. Many of its games were released in an unfinished state, and received largely negative critical response. The company also produced its own Nintendo Entertainment System hardware clones, such as the Q-Boy. 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 developer and publisher for both consoles. With the exception of the latter two handhelds, all of Thin Chen's games were produced without license from the console manufacturers.
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.
