Unite Lucky Technology Co., Ltd (also known as Gen Ching & Cangxin Technology, 倉信科技股份有限公司) was a Taiwanese company which released a number of Mega Drive games, Famicom multicarts, Famiclones and other products, mostly under the name X Boy. Coolboy while they have similar products. It is only their name that is a reference to this company.
The company was officially registered on 22nd July 1986 and dissolved on 9th April 2010 with NT$45,000,000 (approx. USD $1,500,000) capital, but had seemingly stopped releasing games or related products some time previously - its last known activities were as an importer of home appliances.
