A metadata file consists of Collection and Game entries.

A Collection defines which files in a directory (and its subdirectories) should be treated as games, and thus appear in Pegasus. It can also store default parameters, such as how to launch the games (eg. open in emulator X), or default assets assigned for them. All games are grouped into collections, but one game can belong to as many collections as you wish.

A Game entry stores game-specific information, such as developer, release date or description. If a game need a special way to get launched, it can also be set here. A Game may consist of multiple files (eg. multiple discs), optionally with custom parameters like name or special launch command.

Both entry types are a series of data fields in key: value format:

collection: PlayStation
extensions: iso
files:
  specialgame1.bin
  specialgame2.ext
ignore-file: buggygame.iso
launch: myemulator "{file.path}"


game: Final Fantasy VII
files:
  ffvii_disc1.iso
  ffvii_disc2.iso
developer: Square
genre: Role-playing
players: 1

• Keys are case insensitive, so title, Title and TitLe are the same. They always start an the beginning of the lines.
• Values have three possible types:
  • single line text: starts and ends in the same line as the Key.
  • multiline (flowing) text: the text continues for multiple lines. The lines after the first one start with at least one space. Empty lines can be represented with a single dot (.) as their content.
  • list: a list of items, with each item on a separate line. Like with flowing text, each of them start with at least one space.
• Lines starting with # are comments and will be ignored.

Collection entries start with a Collection: <collection name> data field, while Games with Game: <game title>.
