Thank you for viewing. This listing is for the software only, without the box or case. It is unused since purchase, so operation has not been confirmed. Some models (low voltage, especially battery-powered types) may not work. This was the case for a buyer who left a negative review. Some of the installed software appears to have bugs. MARIO IN ZEBES is a game where you play as Mario using Samus, and GIABBIT is a game where you control Mario in a Tigers uniform and play against Jabbit and Sister in golf, and this software is particularly recommended. If you have any questions about the product, feel free to ask. Also, I am open to price negotiations (excluding significant discounts), although I may not be able to meet your request. Please include your desired price when negotiating. Please refrain from commenting if you are just browsing and not considering a purchase. Regarding transactions: * First, please also see my profile. * I will not respond to offers that simply state a desired price. This is because many people don't follow through with the purchase. * I will not respond to generic discount comments. Please state your desired price. * If, after agreeing on a price, you renegotiate, I will immediately block you. * Due to a past instance of reselling without inventory, if you do not respond to a price negotiation within a certain time, I will delete my reply. * This is a privately owned item. Regardless of whether it is new, unused, or in good condition, there may be minor scratches or oversights in addition to what is described. * Please refrain from purchasing if you expect the same level of service as in a store, are overly sensitive, or do not understand used items. * Please ask any questions you may have before purchasing. Please make your purchase only after you are satisfied. * To prevent tampering, cancellations, returns, and exchanges are not accepted after purchase, so please purchase carefully. * To prevent trouble, I may delete bids from new users or those with many negative reviews, or even those with few reviews depending on the content of the reviews. * Packaging for shipping will primarily be recycled cardboard, etc.
