Maniac Mansion was the first game to use the SCUMM scripting language, which is in fact an acronym for Script Creation Utility for Maniac Mansion. The game follows Dave Miller and a group of his friends as they break into a strange mansion in an attempt to rescue Dave's girlfriend Sandy and stop the evil purple meteor from taking over the world. The game has a group of six characters to choose from (Dave must always be in your party), and multiple possible endings. It belongs to Maniac Mansion series.

Game Variants

The DOS versions came in two variations, a 16 color EGA version and an "enhanced version" with higher resolution EGA graphics.

The Nintendo Entertainment System version featured additional music for cut-scenes and themes for each playable character. It also contained many changes from the original due to standards and practices at Nintendo, such as the removal of the statue on the second floor and the changing of several words Nintendo found inappropriate. The Famicom version of Maniac Mansion, released exclusively in Japan did not use the SCUMM engine.

Maniac Mansion is included in Day of the Tentacle. The English version contains the V1 DOS version while non-English versions are V2 DOS. If you have the Macintosh version of Day of the Tentacle you will need to extract the *.LFL files from the Day of the Tentacle Data file using 'extract_scumm_mac'.

Russian PRCA localization is distributed in 2 forms:

  • Patcher by PRCA Clickteam-based patcher. You can place the file mm_ega_rus_1.0.exe mm_ega_rus_1.1.exe in the directory with English version or manually run it under windows.
  • Patcher by ENPY. You can either run it under windows or unpack modified files using innoextract and copy them replacing original files. Password is M49EBVP8360kX82tj8bNSguokMlGNgaY221VEldKB0Z40tK8RMMDTS26n9S05I58

In either case after patching/extracting or just adding Clickteam-based exe files are usable on any platform


Required data files

For more information on how ScummVM uses game data files, see the user documentation.

Amiga, Atari ST, Macintosh, PC

  • *.LFL

Apple II

  • Rename disk image 1 to maniac1.dsk.
  • Rename disk image 2 to maniac2.dsk.

Commodore 64

  • Rename disk image 1 to maniac1.d64.
  • Rename disk image 2 to maniac2.d64.

Commodore 64 Demo

  • Rename disk image to maniacdemo.d64.


Supported versions are English GB (E), French (F), German (G), Swedish (SW) and English US (U). ScummVM requires just the PRG section to run and not the whole ROM.

In order to get the game working, you will have to strip out the first 16 bytes from the ROM you are trying to work with. Any hex editor will work as long as you are able to copy/paste. After you open the ROM with the hex editor, copy everything from the second row (17th byte) to the end. After you do this, paste it to a new hex file. Name the new file "Maniac Mansion (XX).prg" while XX stands for the version you are working with (E, F, G, SW, or U). The final size should be exactly 262144 bytes.

If you add the game manually make sure that the platform is set to NES.

Most common mistakes which prevents the game from running:

  • Bad file
  • ROM extracted with the 0.7.0 tools
  • You try to feed ScummVM with the FULL ROM and not just the PRG section.

It is also possible to extract the separate LFL files from the PRG section. To do so use the 'extract_mm_nes' utility from the tools package.
