Here are the most common solutions, ranging from quick fixes to more permanent, technical methods. 1. The "Trust" Prompt (Easiest)
And if you’re a dev: decide whether you want security or freedom, and set config.use_save_token accordingly.
Ren'Py save files use the format, which is highly flexible but can be used to execute arbitrary code on a computer if the file is maliciously modified.
If you just want to get past the error yourself, you can "trust" the save: When the warning appears, select to trust the creator. Once loaded, renpy this save was created on a different device link
Thankfully, moving your progress across devices is not only possible but relatively simple. This guide explains why the message appears and provides clear, step-by-step methods to transfer your saves safely.
To protect users, the engine generates cryptographic security keys unique to your specific machine. If you copy a save file from a mobile phone, a friend, or an online save editor, the engine notices the digital signature does not match your system and triggers a warning. How to Bypass the "Different Device" Block
If the developer left the developer console enabled, you can bypass checks. Open the game and press Shift + O to open the console. Here are the most common solutions, ranging from
Ensure your cloud client copies both the .save files and the persistent data file to maintain full compatibility. Troubleshooting Common Mismatches
Use Ren'Py Sync , a built-in SDK feature that allows secure transfer of saves and persistent data via a 10-character code.
To prevent future errors, make sure to:
If you move a save file between computers (e.g., from a phone to a PC or from a friend's device), Ren'Py detects the mismatch and asks if you trust the source. User Experience and Impact
If you are a player encountering this issue, follow these steps based on your device:
