Classic Game Boy Games: Pokemon Green, Yellow, and Silver x2 As shown in the photos, these are software cartridges only. There are two copies of Silver. Please check the photos. I have confirmed that they boot up to the start screen, but I haven't tested them for extended play. Therefore, I haven't been able to check the save function. Please understand that I cannot be responsible if the games do not work on your Game Boy. These are old items. Please consider this item if you understand that it has been stored at home by a private seller, is used, and has been inspected by an amateur. There may be oversights. Please refrain from purchasing if you are very particular about the item's condition. Please read my profile before purchasing. (*´꒳`*)
