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.
