Pegasus Front-end #

Moonlight | Wolf

Pegasus is a powerful and flexible frontend for launching games, similar to EmulationStation. It provides a unified interface for interacting with various emulators, eliminating the need to manage multiple emulator interfaces separately.

Getting Started #

ROM Directory Structure #

By default, Pegasus is configured to look for ROMs in the /ROMs directory, with subdirectories for each platform. You can either create the ROM directories in the format below or edit Pegasus to use your preferred location.

Setting Up ROM Directories #

To make your roms accessible to Pegasus within the container, you need to create a bind mount that maps your host ROM folder to the /ROMs directory in the container. This is done by editing the config.toml file; ex:

mounts = [
    "/mnt/PATH_TO_ROMS_IN_YOUR_HOST/:/ROMs/:rw" # <-- EDIT HERE
]

Special Notes #

Setting up the `pegasus.metadata.txt` file #

There is a rom_launcher.sh script to make life easier. When using it, as long as you use the same folder name used for the ROM it’ll be able to find it. For example, for PS3:

collection: Sony Playstation 3
shortname: ps3
command: /Applications/launchers/rom_launcher.sh ps3 "{file.path}"

...

PS3 games #

ISOs are supported! Just use the above rom_launcher.sh script.

ScummVM #

ScummVM will work with zip files if you use the rom_launcher.sh script!

You must first prepare the zip file for this to work correctly:

Add the complete game in the root of the zip file

Add a *.scummvm file inside of the root of the zip file.

This file must contain the official “name” that ScummVM associates with this game

This name can be found in the following yaml file

It is the id portion that comes after the :.

For example:

  -
    id: 'scumm:tentacle'
    name: 'Maniac Mansion: Day of the Tentacle'
    engine_id: scumm
    company_id: lucasarts
    year: '1993'
    moby_id: '719'
    steam_id: ''
    gog_id: ''
    zoom_id: ''
    additional_stores: ''
    datafiles: Day_of_the_Tentacle
    wikipedia_page: Day_of_the_Tentacle
    series_id: maniac

tentacle would be what you would put on the first line of the *.scummvm file

Customization #

Theming #

Pegasus supports extensive customization through themes. You can change the look and feel of your frontend to suit your preferences.

For a demonstration of different themes, watch this https://www.youtube.com/watch?v=WYAgfutLbVE[YouTube video].
Browse and download themes from the official https://pegasus-frontend.org/tools/themes/[Pegasus Themes Gallery].

To install a theme, you need to launch the Pegasus app at least once, then download the theme and place in:

<hostapps_folder>/Pegasus/.config/pegasus-frontend/themes

On the next Pegasus launch, you will be able to select the theme from within the settings.
