If you’ve ever transferred a Ren’Py save file from one computer to another—or tried to load a cloud save on a new device—you might have been greeted by this frustrating message:
This save was created on a different device. Loading it may not work correctly. renpy this save was created on a different device link
Ren’Py then refuses to load the save. But why? And more importantly, how do you bypass it? If you’ve ever transferred a Ren’Py save file
Let’s break it down.
Inside the game's specific folder, you will find a file named persistent (no extension). This binary file contains the unique key for that game on that device. Copy this file. This save was created on a different device
If you have developer console access (enable it in Ren'Py settings or gui.rpy), you can bypass the lock manually. This does not "link" the devices, but removes the barrier.
Developer Tip: You can add a custom "Import Save" button to your game by bypassing the validate_save function in 00saveload.rpy, but this requires editing the engine source.
