Even though it is 2010 not 1985, a new regular Nintendo game came out today

From this Joystiq post:

Battle Kid: Fortress of Peril, the new NES platformer (!) by Sivak Games, was officially released on an honest-to-goodness NES cartridge yesterday. The game, inspired by super-hard games like I Wanna Be the Guy, contains over 550 rooms and 8 bosses, and comes on a translucent green cartridge that is designed to work in any region's NES.
