I bought some new GG software at the time and found it in my closet.
The box has a slight crease at the top as shown in the photo. The bottom is not open so it is beautiful.
The instruction manual is a little scratchy, but it's generally in good condition.

Golden Silver, the legendary god of destruction who once brought the world to the brink of destruction, was sealed on the moon by the Gunstars after a fierce battle. As time passes, Gray, the commander of a dictatorial nation that calls itself the Empire, begins to excavate and steal the four secret stones and the ark necessary for resurrection in order to revive this legendary God of Destruction with great power. . Meanwhile, the Gunstars boys, who had gone into a long sleep after sealing away Golden Silver, were discovered and awakened by Dr. Brown, who happened to be working on an excavation. Dr. Brown hears about the tragic battle that took place in the past from the revived Gunstars Red, Blue, and Yellow, and promises to defect from the Empire and cooperate with them. In order to protect the world and prevent the resurrection of Golden Silver, the Gunstars stand up again and a new battle against the Imperial Army has begun.
