Introduction
CloudRetro provides an open-source cloud gaming platform for retro games. It started as an experiment for testing cloud
gaming performance with WebRTC and Libretro, and now it
aims to deliver the most modern and convenient gaming experience through the technology.
Theoretically, in cloud gaming, games are run on remote servers and media are streamed to the player optimally to ensure
the most comfortable user interaction. It opens the ability to play any retro games on web-browser directly, which are
fully compatible with multi-platform like Desktop, Android, IOS.
In ideal network condition and less resource contention on servers, the game will run smoothly as in the video demo.
Because I only hosted the platform on limited servers in US East, US West, Eu, Singapore, you may experience some
latency issues + connection problem. You can try hosting the service following the instruction the next section to have
a better sense of performance.
Feature
- Cloud gaming: Game logic and storage is hosted on cloud service. It reduces the cumbersome of game
initialization. Images and audio are streamed to user in the most optimal way using advanced encoding technology.
- Cross-platform compatibility: The game is run on web browser, the most universal built-in app. No console,
plugin, external app or devices are needed.
- Emulator agnostic: The game can be played directly without any extra effort to set up the gaming emulator or
platform.
- Collaborate gameplay: Follow the idea of
crowdplay(TwitchPlaysPokemon), multiple players can play
the same game together by addressing the same deeplink. The game experience is powered by cloud-gaming, so the game
is much smoother. Check CrowdPlay section
- Online multiplayer: The first time in history, you can play multiplayer on Retro games online. You can try
Samurai Showndown with 2 players for fighting game example.
- Horizontally scaled: The infrastructure is designed to be able to scale under high traffic by adding more
instances.
- Cloud storage: Game state is storing on online storage, so you can come back and continue playing your incomplete
game later.
Development environment
- Install Go
- Install GStreamer
# Ubuntu / Windows (WSL2)
apt-get install -y make gcc pkg-config libgstreamer1.0-dev libgstreamer-plugins-base1.0-dev gstreamer1.0-plugins-good
# macOS
brew install pkg-config gstreamer gst-plugins-base gst-plugins-good
# Windows (MSYS2)
pacman -Sy --noconfirm --needed git make mingw-w64-ucrt-x86_64-{gcc,pkgconf,gstreamer,gst-plugins-base,gst-plugins-good}
Because the coordinator and workers need to run simultaneously. Workers connect to the coordinator.
- Script
make dev.run- The scripts spawns 2 processes one in the background and one in foreground
- Manual
- Need to run coordinator and worker separately in two session
go run cmd/coordinator/main.go - spawn coordinatorgo run cmd/worker/main.go --coordinatorhost localhost:8000 - spawn workers connecting to coordinator
Additionally, you may install and configure an X Server display in order to be able to run OpenGL cores.
See the docker-compose.yml file for Xvfb example config.
Run with Docker
Use makefile script: make dev.run-docker or Docker Compose directly: docker compose up --build.
It will spawn a docker environment and you can access the service on localhost:8000.
Configuration
The default configuration file is stored in the pkg/config/config.yaml file.
This configuration file will be embedded into the applications and loaded automatically during startup.
In order to change the default parameters you can specify environment variables with the CLOUD_GAME_ prefix, or place
a custom config.yaml file into one of these places: just near the application, .cr folder in user’s home, or
specify own directory with -w-conf application param (worker -w-conf /usr/conf).
Deployment
See an example of deployment scripts if you want to try to host your own cloud-retro copy in the
cloud. This script (deploy-app.sh) allows pushing configured application to the group of servers automatically. The
cloud server should be any Debian-based system with the docker-compose
application installed.

FAQ
Crowd Play, play game together
By clicking these deep link, you can join the game directly and play it together with other people.
And you can host the new game by yourself by accessing cloudretro.io and click “share” button
to generate a permanent link to your game.
