Great deal with a set purchase!! This is a working Nintendo 64 Mario Kart for sale. 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 +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 these issues. It will be carefully packaged and shipped.
