Core Graphics + CD-ROM operation confirmed. Since it's old, I'm selling it as junk. Please refrain from purchasing if you are a perfectionist. The game used for operation check is not included in the set. CD-ROM unit + controller x 2 (operation confirmed) + multi-tap + Super System Card (defective?) + System Card (operation confirmed) + adapter + cable. My knowledge of CD-ROM2 is limited, so please comment if you have any concerns.
