User gzip continues to hack away at Maniac Mansion for the NES, this time adding a custom puzzle chain which adds new objects, modifies existing objects, and has a payoff of an entirely new room which contains some fun graphics. These changes serve as a proof of concept for producing new games using the SCUMM engine on the NES, and is also another step towards a full disassembly of the game. This all comes as part of the Maniac Mansion Decoded hack, now with full source code available on Github.
