Software, instruction manual, card case, case We have confirmed the operation, but as the software is several years old, we cannot guarantee its startup or operation at the buyer's end. Please understand this before purchasing. * The card case has stickiness due to aging. * As this is a used item, there are scratches and stains. We do not recommend this to those who are concerned about minor details or are神経質な (fastidious/sensitive). Thank you. #SEGA #MasterSystem
