The cancelled NES port of Chip's Challenge, originally for the Atari Lynx. A build, labeled as "V0.924B" on the title screen, was released by Lost Levels on November 13, 2015.
The normal level sequence contains only 132 levels (one exclusive to the NES port), plus 4 secret levels. That leaves 13 levels from the original game inaccessible.
Entering the password HARD takes the player to Forced Entry, from which they can access the other removed levels: Blobnet, Mishmesh, Scavenger Hunt, On the Rocks, Slo Mo, Cityblock, Colony, Icehouse, Block N Roll, Blobdance, Pain, and Yorkhouse.
The idea of this arcade game is deceptively simple: Guide a marble down a path without hitting any obstacles or straying off the course. The game is viewed from an isometric perspective, which makes it harder to stay focused on the direction the ball is to follow. There are tight corridors to follow and enemies to avoid. There is a 2-player mode in which players must race to the finish; otherwise you're racing against the clock.
NES Port of Battle Chess
Did someone tell you chess is a civilized game played by civilized people? Forget it. Chess is war - a ruthless, cutthroat battle where one warrior lives to fight again and the other is left on the battlefield. With BATTLE CHESS you don't just imagine the battles, you experience them! You'll hear the clank of armor, as you watch dramatic, 3-dimensional animations of courageous heroes fight to protect their king. BATTLE CHESS is the most incredible chess game you've ever seen - where empires can be won - or lost!
An improvement mod for Cheetahmen II that fixes most major glitches in the game, including allowing access to the final levels of the game after the level 3 boss.
