Maniac Mansion (DOS)

The Day Before The Tentacle!

Debug Mode#

Both versions released for DOS have a hidden debug mode. The method of accessing it is mostly the same (enter a command and press F7), but the command itself is different between versions: on the original version, the command is !a%ifyou*ve; on the enhanced version, the command is instead *ch4mysocks (use the typewriter keys on the keys on the keyboard for entering *, not the key on the numeric keypad).

Commands#

Please elaborate. Having more detail is always a good thing. Specifically: What does "something" mean?

• Shift-D - Displays the running scripts
• Shift-G - Goto room
• Shift-O - Get object in room
• Shift-S - Set variable
• Shift-Z - Display hex data from memory
• Shift-/ - "Something"
• Esc - Redraw screen

Unused Death#

Watch on YouTubeNormally, after growing the man-eating plant with radioactive water, the player is supposed to use a can of Pepsi to calm it enough to climb it to the observatory. However, by using debug the player can skip this and access the room above. If the player then leaves down the hatch, they will disappear and be eaten by the plant. This suggests that originally the player could climb the plant prematurely before giving it the Pepsi, resulting in a death. It is unknown why this was removed.
