Maniac Mansion Decoded

Maniac Mansion Decoded
Hack of Maniac Mansion

 
 
Description:

Maniac Mansion for the Nintendo Entertainment System uses a simple compression scheme for it's graphics and layouts known as Run Length Encoding (RLE). The encoding makes it very difficult to edit any of the layouts or graphics in the game.

This hack expands the ROM and decodes all of the encoded data to make it very easy to edit graphics and layouts. The number of tiles for each room is also maximized to make room for new graphics. A lot of space is freed up as a result which makes it easier to edit game objects as well as text. As such, this hack can serve as a base for new hacks like Maniac Mansion Uncensored.

As a proof of concept, a new puzzle chain is included which modifies existing objects, adds new objects, and adds a whole new room as a final payoff. It does not affect the rest of the game. You can select the base patch to omit this addition.

The hack also includes the Maniac Mansion Mouse Hack and fixes a few glitches in the game:
  • The glitched graphics in the room under the house are fixed
  • The glitched coin box graphics in the arcade are fixed
  • The leftover pennant object in Weird Ed's room is removed
  • The leftover keypad object in the hallway is removed
  • The fence mask is fixed in the starting screen so that the player is completely behind it
  • The colors for the right-side gargoyle on the stairs are fixed
  • The border color is fixed when selecting Michael on the character select screen
  • The glitched graphics for the developer under the house are fixed
  • The interactivity for the radioactive slime in the basement is restored
Please PM gzip with any glitches or other feedback.
