About
Maniac Mansion is Lucasfilm Games' 1987 adventure. Dave and two friends he picks go into Dr. Fred's mansion to rescue Sandy from the Edison family and the purple meteor. It was the first game on the SCUMM engine, and the verbs on the bottom of the screen replaced typing.
This is the game running on Michele Di Paola's SCUMM version 2 interpreter for the Apple IIGS, written in 65816 assembly in 2026, working with Claude. It plays from the kid select screen into the mansion with walking and pathfinding, the verb panel, inventory, dialogue, scrolling rooms, the flashlight in dark rooms, and the game's own save and load screen. Sound effects are the Amiga release's samples on the Ensoniq, and there is no music.
The volume is named SCUMM and holds the interpreter plus two folders, MM and ZAK, with each game's own .LFL files. Mount it next to a GS/OS boot disk, launch SCUMM from the Finder, and pick L00.LFL in the folder of the game you want. Esc skips a cutscene where the script allows it, Space pauses, Q asks before quitting, and Apple-8 asks before restarting. This game is in the MM folder. The volume is shared with Zak McKracken, and the SCUMM v2 page covers both.
