New battery replaced, maintenance completed. This is a Kirby's Dream Course from a later production run. It's quite rare, as they're not often seen. Tested and working on a Super Famicom. Disinfected with anhydrous ethanol. Please assess the condition of the cartridge from the images. Please purchase only if you are satisfied. The cartridge contacts have been cleaned and polished with anhydrous ethanol and polishing compound to remove dirt. While it starts almost immediately on my console after this maintenance, there is no guarantee it will start immediately on other consoles. This is an old product from decades ago, so it may require a few insertions and removals to start.
