This is a genuine copy of Namcot's "Wrestleball" for the Sega Mega Drive. It is a "Shouhin Mihon" (Not For Sale) store display sample copy — the only difference from a standard retail copy is this sticker/label; it is otherwise a genuine, complete, working copy of the game, as pictured.
It is complete with the case, manual, and cartridge, as pictured. The seller has confirmed it is working. It is in used condition consistent with its age, so please review all photos closely.
