There is one NES game that arent listed in the guide:
Snow Board (or Snowboard) Challenge.
NES code: NES-SH-ESP
It was made (or atleast published) by Activision. Its an official NES game, it have "Seal of Quality" infront of the box. It says 1991 at the back of the box so i guess that is the year it was released. It was released in Spain atleast. Possibly that the game was released in the US also, but under a diffrent name.
