Game Boy Player Startup Disc (with instruction manual) I haven't confirmed its operation because I don't have a GameCube. Please check the condition in the photos. There is a faint mark on the back cover of the case where "Game Boy Player" was written. I do not accept claims such as "it doesn't start" after purchase. Please understand this before you buy. The case will be wrapped in cushioning material and packaged to prevent water damage for shipping. Instant purchase is welcome.
