Please read the profile before purchasing. Sega Mark III Kenseiden I have confirmed the loading and opening sequence on a Retro Freak. I do not guarantee that it will work on the buyer's system (including Retro Freak), nor do I guarantee full functionality. Please understand this before purchasing. Please check the condition in the images. Please note that the battery and save function status are unknown. It will be shipped via Yu-Packet Plus to prevent damage. Returns and refunds (to prevent swapping, etc.) are not accepted. If you have any concerns, please refrain from purchasing from me and consider purchasing from other sellers or stores.
