Pegasus Frontend

Pegasus is a graphical frontend for browsing your game library and launching all kinds of emulators from the same place. It's focusing on customizability, cross platform support (including embedded) and high performance.

Linux (X11/RPi1/RPi2) build status Windows build status Windows build status 2 Coverity Scan status Codacy status GPLv3 license


Open source and cross platform: runs on Linux, Windows, Mac, all Raspberries, Odroids and possibly on other devices. Hardware accelerated and works with or without X11. It may even run on phones and tablets too.

Full control over the UI: you can completely change everything that is on the screen, add or remove UI elements, menu screens, whatever. Want to make it look like Kodi? Steam? Any other launcher? No problem. You can even run your custom shader code.

ES2 backward compatibility: Pegasus can use EmulationStation's gamelist files, no need to invent a new set of tools.

Features you'd expect: Gamepad support and config. Multiple aspect ratio support. Portable mode support. Live theme reload. Visible system informations. A clock in the corner.


At the moment, this project is still in alpha. You can find the current unstable releases and the latest automatic builds here. You can also build the program manually from its source code.

Debian/Ubuntu: for 64-bit desktops, the latest version can be installed like this:

# Add the repository
curl https://bintray.com/user/downloadSubjectPublicKey?username=bintray | sudo apt-key add -
sudo add-apt-repository 'deb https://dl.bintray.com/mmatyas/deb testing main'

# Update and install
sudo apt update
sudo apt install pegasus-frontend

Runtime dependencies

While the releases try to include most required dependencies, on some platforms you might need to install additional packages.

  • Linux: a distro not older than Ubuntu 14.04 or Debian Wheezy is recommended. The dependencies are Fontconfig and GStreamer 1.x (fontconfig gstreamer1.0-alsa gstreamer1.0-libav gstreamer1.0-plugins-good).
  • Windows: all dependencies included, should work on anything between Windows 7 and 10.

Building from source

Build dependencies

  • C++11 compatible compiler
  • Qt 5.8 or later (5.9 recommended), with the following modules:
    • QML and QtQuick2
    • Multimedia
    • SVG
    • Gamepad
    • SQL (SQLite v3)

For more information, please see the detailed build guide.

Downloading the source

The project uses Git submodules. If you cloned the repository recursively, they are automatically cloned as well. If you did not, you can do it manually like this:

# call this after every repo update
git submodule update --init


You can use any Qt-compatible IDEs, eg. Qt Creator to build the project, or you can manually invoke:

mkdir build && cd build
qmake ..  # qmake [params] [project path], see below
make install  # optional

QMake parameters

Additional parameters are available for QMake:

  • INSTALLDIR: where to make install the program. Defaults to /opt/pegasus-frontend or C:\pegasus-frontend.
