Great deal with set purchase!! This is a listing for a working Nintendo 64 Star Kirby game. It has been inspected and cleaned, and is fully functional. It has not been disassembled for cleaning. As an option, I can replace the internal battery with a new one for an additional 250 yen (per game). Please comment if you would like this. As it is an old item, there may be some dirt and yellowing. Please refrain from purchasing if you are sensitive to this. I will pack it carefully and ship it.
