This is a set of 2 Nintendo GameCube main units. I used to use a Game Boy Player, All the screws on the back are missing. Also, nothing other than the two main units is included. Also, as shown in the second photo, the back cover has been replaced with a black one. I was able to confirm that it boots up and that Pikmin 2 could be played initially, but Since this is a replacement item, there must have been some kind of malfunction. Please purchase with the understanding that it is a junk item.
