Guides / Relay
From the first file to your next save.
Import your own games, transfer from a computer, and keep your progress with iCloud or Relay Sync.
Import your games
Keep an original copy of your own game files. On iPhone or iPad, choose Add games and select files in Files; on Mac, use File → Import, Command-I or drag into the window. Read the result for each file: added, already in your library or rejected. Renaming an extension does not convert a game.
Saves, iCloud and Relay Sync
Keep your library, saves and play history together with a Relay Account. Relay Sync gives you 100 GB; Sync+ gives you 500 GB. Both include Relay Pro while your subscription is active. Game-file sync is your choice.
Send games from a computer
Choose your device. Drop your files or a whole folder. Relay adds supported games to your library, even when they come from different systems.

Choose an emulator for your games
Start with your actual games, file formats and devices. Check the required BIOS, controller support, save behavior, licences and privacy policy. Try a game and a device switch before moving your whole library. This guide is written by Relay; it makes no competitor ranking or performance claim.
