Your games (the "roms") go in the share/roms/ folder, with one subfolder per console (snes, megadrive, psx…). Recalbox automatically displays the systems for which games are present.
Recalbox comes with royalty-free games. For everything else, you must own the original games: neither Recalbox nor the wiki provides roms.
Is your Recalbox connected to the network? Then from your computer:
\\RECALBOX (or \\ followed by its IP address) in the address bar.Go → Connect to Server → smb://recalbox.local.smb://recalbox.local in your file manager.share folder → roms → the folder of the target console.START → SYSTEM-LISTS & GAMELISTS SETTINGS → UPDATE GAMES LISTS — your games appear.Windows doesn't show or open
\\RECALBOX? A classic side effect of Windows updates: see the dedicated troubleshooting page.
recalbox/roms/….SHARE partition is exFAT, readable everywhere — insert the card into your computer and copy into roms/….On the next boot, the games are detected automatically.

DO NOT SCAN NEW GAMESis enabled (MAIN MENU>ADVANCED SETTINGS>BOOT SETTINGS): Recalbox then simply re-reads thegamelist.xmlfiles at boot and ignores the files you added. This is the most frequent cause of "I added games but they do not show up". Run the game list update by hand in that case.
From inside a game list,
START>UPDATE GAMES LISTSrescans that system only: far quicker than a global update when you only added games to one console.
Every folder in roms/ contains a help file listing the accepted formats. The full details per system (extensions, required bios…) are in the Emulators section of the wiki.
