LaunchBox vs RePlayOS

LaunchBox is a game collection frontend and manager for modern PC games and emulated console games. It can import Steam and GOG games, ROM files, and MS-DOS games, then retrieve box art and metadata from its Games Database along with fan art, screenshots, and logos. Collections can be arranged and filtered by genre, platform, ESRB rating, developer, and publisher, with custom status and source fields. The Windows app supports Windows 10 and higher, with Windows 10 and 11 described as fully supported. LaunchBox for Android is free for collections of 100 games or fewer; it shares the games database, media, and portable XML data with Windows, and Windows data can be exported to Android. Premium adds themes, Big Box mode, gamepad automation, startup and pause screens, and display customization. The Regular Windows license costs $30 as a one-time purchase and includes a year of free updates. The maker says Premium is DRM-free and can be deployed to as many personal devices as desired. Windows data can also be moved by copying the app to another folder or computer.

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.
