On your computer. Straight into Relay.
Choose your device. Drop your files or a whole folder. Relay adds supported games to your library, even when they come from different systems.
Relay Pro + a free Relay Account are required.
Files go straight to your device, or through an encrypted EU relay. Relay never stores them.
No transfer size cap. Your device still needs room, and supported formats apply.

Follow every file from sending to import. Two files can travel at once.
If something goes wrong
ZIP accepts stored or deflated files, up to 64 entries, 128 MiB per expanded file and 256 MiB total. Encrypted ZIP and ZIP64 are rejected. If a large game exceeds those limits, extract it locally and import the original file. Transfer itself has no product byte quota; device storage and importer limits still apply.
No. Transfer sends them to your device without storing them online. Your device and browser need to stay open and connected. Game-file sync remains a separate choice in your settings.
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.
