Guides / Relay

Choose an emulator for your games

Choose an emulator for your games. Import your own games, transfer from a computer, and keep your progress with iCloud or Relay Sync.

Choose what fits 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.

Game files

No. Bring the game files you own. Relay never bundles games or firmware, and never links to places that do.

iCloud and Relay Sync

Your library, saves, and play history. Game-file sync is free and opt-in. It all lives in your private iCloud storage.

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.

Staying with Apple? Your private iCloud sync remains free. Relay Sync is a separate, optional storage plan.

Relay for Android is coming. Relay Sync connects the Apple and Android ecosystems: when the Android app arrives, use the same Relay Account to carry your library and progress between them.
