New battery holder type replacement, maintenance completed. Using a test battery, startup and operation have been confirmed on a Super Famicom. Disinfected with anhydrous ethanol. We would appreciate it if you could judge the condition of the cartridge from the images. Please purchase only if you are satisfied. Due to the special PLG system, Daikaiju Monogatari 2, which consumes batteries quickly, has a battery holder installed. If you have a special screwdriver, you can replace the battery yourself. The cartridge terminals have been polished and cleaned using anhydrous ethanol and a polishing agent to remove dirt. Maintenance has been performed to the point where it starts almost immediately on our console, but there is no guarantee of immediate startup on compatible consoles or other consoles. As this is an old product from decades ago, it may not start without inserting and removing it several times. A new battery will be installed before shipping.
