    CloudRetro

    CloudRetro

    Web-based Cloud Gaming service for Retro Game

    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 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 a 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.
