Nintendo DS Tamagotchi no Pichi Pichi Omicchii software. I confirmed that it works on a Nintendo DS Lite, but it can also be played on other consoles such as the New 3DS LL and 2DS (the data from that time was still saved). It's an old game, but there are no noticeable scratches or stains, and the case and instruction manual have been kept in good condition. ( ´∀｀) Recommended for those who played it when it was first released, those who are playing it for the first time, and those who want to enjoy it at a leisurely pace. Thank you very much! ♫
