Installation

Required data files

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

WARNING: Unlike other games, SCI games have significant variation in the naming of required files.

They also can load supplementary files by resource maps, so it is recommended to keep all files in the game data directory from the CD.

Unless otherwise specified, do NOT remove any file from the directory, even if it does not appear on the following list, since this will likely cause weird bugs.

Copy all files to the game directory. Some games need additional work:

Floppy games with RESOURCE.p01, p02, etc. and/or RESOURCE.a01, a02, etc. files

• Concatenate all RESOURCE.p0* files to RESOURCE.000 (e.g. copy /b RESOURCE.p0* RESOURCE.000 on Windows, or cat RESOURCE.p0* > RESOURCE.000 on *nix).
• Concatenate all RESOURCE.a0* files to RESOURCE.AUD (e.g. copy /b RESOURCE.a0* RESOURCE.AUD on Windows, or cat RESOURCE.a0* > RESOURCE.AUD on *nix).

Simultaneous speech and subtitles

Certain CD versions of Sierra SCI games had both speech and text resources. In ScummVM, it is possible to enjoy a combined mode, where both speech and text are shown at the same time.

Speech and text can be toggled via the "Display Mode" button in the options dialog, or via ScummVM's audio options.
