Shipping will be via standard mail (excluding Saturdays, Sundays, and holidays). ⚠️Please refrain from purchasing if you are particular about simple packaging. ⚠️Shipping will be in an envelope, without bubble wrap. Waterproofing will be provided. (Packaging will be simple, and recycled materials may be used.) ⚠️(For Game Boy software under 3,000 yen) Since most items are shipped via standard mail, I am not responsible for any undelivered accidents. If you require compensation, I will change to Nekopos (anonymous shipping) for an additional 150 yen. Software only. Operation has been confirmed. The terminals have been cleaned using a contact cleaner. Please note that there may be cases where the software does not start properly due to compatibility issues with the main unit, but I cannot guarantee this. Battery backup function is not guaranteed. ※Since this is used software, there may be cases where reading is poor. I always check the operation before shipping. ※Please purchase with the understanding that this is a used item and has been stored at home. Please refrain from purchasing if you are nervous or seeking perfection.
