SCUMMVM(6)

NAME
scummvm - adventure and role-playing game interpreter

SYNOPSIS
scummvm [OPTIONS] [GAME]

DESCRIPTION
scummvm is an interpreter that will play numerous adventure and role-playing games based on a variety of game engines.

GAME is a short name of game to load. This can be either a built-in gameid (as given by --list-games), or a user-configured target (as given by --list-targets).

OPTIONS
The meaning of most long options (that is, those options starting with a double-dash) can be inverted by prefixing them with no-. For example, --no-aspect-ratio will turn aspect ratio correction off. This is useful if you want to override a setting in the configuration file.

-a | --add
    Add all games from current or specified (with --path=PATH) directory. If --game=ID is passed, only the game with id ID is added.

    See also --detect.
