RetroArch vs RetroFE

RetroArch is a frontend for emulators, game engines, and media players, bringing them under a unified settings system. The RetroArch/Libretro project includes more than 200 cores across those categories. Its menu can group scanned games by system and display thumbnails and animated backgrounds. Common game controllers configure automatically when plugged in, and button actions can also be assigned manually.

Stackable shaders can change rendered graphics or imitate the look of CRT monitors. Built-in netplay supports hosting or joining network gaming sessions, including spectator mode. RetroArch can record gameplay to video files and stream games to Twitch or YouTube. Versions are listed for Windows, Linux, Android, iOS, macOS, and web browsers. RetroArch is free and open source under GPL version 3; the libretro API uses an MIT license. Features differ by platform and store version: the browser edition has lower performance and fewer capabilities than the full version, while Steam lacks Core Updater and thumbnail scraping and offers a selected core set.

RetroFE is a free, open-source front end for displaying, selecting and launching games, videos and programs, commonly used for game emulation. Collections arrange games and menu items into systems and submenus, and can show media such as box art, screenshots, logos and videos. Layouts set the front end’s appearance, with the option for collections to use their own layouts. Launcher configuration specifies an executable and arguments for starting an emulator, application or game; per-game launcher settings can override a collection’s default. Controls such as up, down, select and back are configured in a controls file. Its game information database can hold details including year, manufacturer, genre and player count. Setup involves editing global settings and controls files, then adding or editing collections. Full releases include a 32-bit Windows executable and a 64-bit Linux executable. Windows requires a recent Visual C++ Redistributable for Visual Studio; some Linux distributions may require compiling from source. macOS users need to compile their own executable. Community-made themes are available for installation in the layouts directory, and the maker points users to forums and describes community support.
