Lakka vs RetroHub

Lakka is a lightweight Linux distribution that turns a small computer into a retrogaming console. It is built on LibreELEC and RetroArch, with RetroArch serving as its graphical interface and providing unified emulator configuration and joypad autoconfiguration. Listed features include automatic controller recognition, rewinding, netplay, and shaders. Official builds target Raspberry Pi, Allwinner, iMX6, Amlogic, and 32-bit and 64-bit PC systems. Installation uses USB images specific to the target hardware, and installation instructions cover GNU/Linux, Windows, and MacOS. The PC version is intended for dedicated hardware and does not support virtualization, dual boot, or CD and DVD installation. Users must supply their own ROMs; documentation also covers BIOS files. Netplay requires both players to use the same ROM, and cores without savestate support cannot use it. Lakka is community-driven and open source, and the listed price is free; required hardware is not included. The project says it remains under heavy development, so bugs, missing features, or unsupported hardware may occur.

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.
