New battery replaced, maintenance complete. Super Famicom: startup, operation, and saving confirmed after new battery replacement. Disinfected with anhydrous ethanol. Please assess the condition of the cartridge from the images. Please purchase only if you are satisfied. In my subjective opinion, the software is in good condition. Those who are concerned about minor imperfections should refrain from purchasing. The cartridge pins have been cleaned and polished with anhydrous ethanol and polishing compound to remove dirt. Maintenance has been performed to the point where it almost always starts up on my console, but there is no guarantee of one-time startup on other consoles. This is an old product from several decades ago, so there is a possibility that you may need to insert and remove it a few times.
