This is Super San Guo Zhi II for the Super Famicom. This is the official Japanese version of the game, made by Nintendo. It still has the import sticker on it, as it was officially imported into Taiwan.
 
Everything is tested and works fine. There is some damage to the back label, and the cartridge is a bit dirty. There is no battery in this cartridge, and the cartridge is missing the two screws on the front.
