Portable storage device for a game machine to mount games

Abstract

The present invention relates to a portable storage device for a game machine to mount games, which includes a portable storage device and a main game machine. The main game machine and the portable storage device are provided with mutual coupling connector interfaces. The connector interface of the portable storage device is further configured with an encoding and decoding unit, which enables processing and transmitting of game files within the portable storage device to the main game machine, after which an execution unit of the main game machine executes the game files and produces an operable user interface, thereby effectively increasing memory capacity of the main game machine. In accordance with such means, the game files of the portable storage device can be mounted on the user interface.
