Nintendo DS Tamagotchi no Puchi Puchi Omisecchi Gohiki ni Soft. I have confirmed that it works on a Nintendo DS Lite. You can also play it on a New 3DS LL or 2DS (the data from back then is still there). There is no case, and only the game cartridge is included. I am selling this at the lowest price among my current listings, with anonymous shipping included. ( ´∀｀) This is recommended for those who haven't played it in a while, those who are playing for the first time, and those who want to play it at a low price. Thank you very much! ♫
