- Brand: NATSUME - Model Name: NAT-N1 - Release Year: 1988 - Game Genre: Adventure I remember it being a very unusual game. This item has been stored at home for a long time. The main unit is missing, so operation has not been confirmed. (Even if it works, the internal battery will likely need to be replaced for backup functionality.) The back and other areas are quite dirty. It is being offered at a low price as a result, so please purchase only if you understand this. Returns and complaints are not accepted, including in the case of non-working condition.
