Batocera vs RetroHub

Batocera Linux is a free, open-source Linux distribution that turns compatible computers and small devices into retro-gaming consoles. It can run from a USB stick or SD card without changing the computer, or be installed permanently. Download builds are listed for desktop PCs, laptops, Intel-based Apple computers, handheld PCs, Raspberry Pi, Odroid boards, and other devices. Batocera supports many consoles, platforms, emulators, and related applications through a front end based on a modified EmulationStation. Its content downloader provides freely distributed ROMs, bezels, music themes, and other enhancements, with packages handled by pacman. Documentation covers Netplay for supported games and integrations including Kodi, RetroAchievements, The Bezel Project, Syncthing, NAS storage, and a web server. Installation requires at least 16 GB of storage; 32 GB is recommended. Batocera focuses on retro gaming and will not implement emulators for current-generation consoles.

RetroHub is a free frontend for organizing, displaying, and launching a retro-game library on Windows, macOS, and Linux. A first-time setup wizard helps configure it, and users can import games and settings from supported frontends. The app supports more than 80 systems and more than 50 emulators, while allowing users to add settings for others; it does not include emulators. Game metadata and media can be customized, and the built-in ScreenScraper feature can identify games by file hash or filename and fetch related information and images. ScreenScraper applies hourly and daily API quotas, and scraped media for a large library may take more than 1 GB of disk space. Users can change themes, and theme development can shape the interface and add features. Inputs include keyboard, mouse, controller, and touch; keyboard and controller actions can be remapped. The interface adapts to screen size and aspect ratio and includes a screen-reader option. RetroAchievements is an optional integration. Source code is MIT-licensed, while official builds use GPLv3 due to bundled third-party libraries.
