G-Factor is a series of VT03-based Famicom cartridges compatible with various Famiclones produced by Yobo Gameware, such as the Factor-5 console. They were released on the North American market in the late 2000s.


The G-Factor cartridges are all 5-in-1 multicarts, the count of "5" possibly being chosen to match the Factor-5 console name. They are about half the size of a standard Famicom cart, likely to indicate they are not backwards-compatible with the original hardware. Each cartridge appears to use the otherwise-uncommon Shenzhen Niutai game library, including a few of the originally-developed games from that set; though the majority of games are Niutai's VT03 hacks of Nice Code titles. Unhacked Nice Code versions and Qi Sheng Long variations are also included.
