Game files
PlayStation is supported in Relay. Disc companions and your own validated BIOS matter; a generic ISO is not automatically a compatible PlayStation game.
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.
Game files
Keep a CUE sheet with every BIN track it references. CHD contains a compressed disc; an M3U playlist groups multiple discs. Preserve relative filenames and send companion files together. PBP, PSP and PlayStation 3 games are outside this PlayStation import path.
BIOS
Supply your own compatible PlayStation firmware through Relay’s firmware setup. The supported BIOS files are scph5500.bin, scph5501.bin and scph5502.bin, each 512 KiB and validated by content. Relay never bundles or downloads proprietary firmware. Firmware setup is local to each device.
Controls and screens
PlayStation, Xbox, MFi, 8BitDo, and other standard Bluetooth controllers. Keyboard on iPad and Mac. No setup.
Save and continue
Save inside the game when it offers that option. A manual Relay state captures a moment in the emulated machine; Auto Resume helps you return after an interruption. Keep Relay open for sync to finish, then check the destination has the expected game and progress before continuing. States require compatible game content and emulator versions.
Two devices disagree? Relay keeps both saves and asks you. Nothing gets overwritten.
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.
