Batocera vs RePlayOS

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.

RePlayOS is a Linux distribution for emulating classic game consoles, arcade machines, and computers through a streamlined libretro frontend. It is built around Raspberry Pi hardware, with listed support for Zero 2, 3A/B/B+, 4B, and 5B models, and works with LCD and CRT screens. Its DynaRes display engine supports native CRT timings, timing changes, CRT profiles, dual-screen modes, and LCD operation at game refresh rates. The system supports more than 700 controllers and up to six players, plus RetroAchievements in compatible cores and games. Replay Control is a companion web app for browsing games, launching them on a TV, managing favorites, and configuring the system over a local network. Compatible cores can use Link Play multiplayer over that network. Alpha Player handles audio and video files, with Raspberry Pi 5 recommended for movies. A small HTTP JSON API provides local or LAN control when enabled, but uses plain HTTP. The public version is free; the frontend is proprietary, with restrictions on modification, standalone redistribution, and unauthorized commercial use.
