RetroArch

RetroArch is an open-source project that uses the Libretro development interface. Libretro allows for the creation of cross-platform applications with rich features such as OpenGL and location support. RetroArch comes with its own collection of applications for entertainment purposes. However, the version available on the Google Play Store does not have the Core Downloader feature, limiting it to 50 cores. If more cores are needed, there is the option to download RetroArch Plus from the Play Store or get the APK from the RetroArch website for the full version. The Play Store version has automatic weekly updates, while the website APK allows for up to 127 cores. RetroArch offers various features such as eye-candy menus, the ability to scan files and add them to game collections, and multiplayer support through NetPlay.
