This section covers everything related to your games: where roms come from, how to pick and organise them, and the quirks of the systems that need specific preparation.
The pages under General topics apply to every system: what a rom or an iso is, which dumping group to choose, how to sort and update your collection, how to handle multi-disc games and how to set up shaders.
Some systems need a specific step: a BIOS to enable, a precise folder structure, a RetroArch subsystem to load… The Guides cover those cases, system by system.
Recalbox can also display games running on another computer on your network, through Moonlight: your PC does the rendering, Recalbox receives the picture and sends the controller inputs back.
For a system's technical sheet (available emulators, required BIOS, accepted extensions), head to the Emulators section instead.
