Sachen also known as Thin Chen Enterprise Co., LTD is a company based in Taiwan. They are mainly known in the far east for thier Famicom and Game Boy multi carts. The Cheif Executive Officer (C.E.O) of Sachen is Mr. Ching Jung Tseng the company was established in 1988 and they are still producing games today.

Sachen is one of the few unlicensed companies that develop and manufacture all there own games. Unfortunately Sachen no longer manufacture 72pin NES cartridges I am guessing due to lack of demand. They are only currently producing Famicom, Game Boy/Color games and accessories.

The NES games were exported to a few countries in Europe, Netherlands and Finland come to mind. But this would have been in very limited quantity. Sachen did how ever sell the writes to some of their games (Little Red Hood, Pyramid, Twin Eagle etc) to unlicensed companies American Video Entertainment (A.V.E) and Home Entertainment Suppliers (H.E.S).
