Downloading and installing

Project Eris version of RetroArch is built by the ModMyClassic team. It may have a different version than RetroArch's current version. As Project Eris is updated, the RetroArch it contains may be close to the current version.


These two versions may contain different contents from each other. While the main purpose of Project Eris may be the Ultimate PlayStation Classic, RetroBoot runs RetroArch directly.
