GameEx vs RetroArch

GameEx is an arcade and emulator front end for MAME, GameBase, Daphne, PC games and command-line emulators, with HTPC features. The site lists original GameEx, GameEx Arcade Edition and GameEx Evolution. Its feature list describes support for nearly any emulator, with advanced MAME support, and compatibility with arcade controls such as X-Arcade, Slik-Stik, JPAC and IPAC, as well as remotes and gamepads. Media features include video and DVD playback, picture viewing, internet radio, a jukebox, a news reader and a YouTube module. Named integrations include Steam, EA Origin, Uplay, iTunes, Windows Media Player, GameBase, GameEx Arcade and the TMDb API. GameEx Online and GameExtender add networked display, remote control and online game statistics. Its listed free plan costs nothing, but commercial use requires each copy to be registered or purchased. The listing includes Android, Linux, macOS and Windows; the maker describes Linux or Mac use through WINE as experimental, while the multiplatform alpha builds may lack features.

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.
