Renpy This Save Was Created On A Different Device Link -

The message "This save was created on a different device. Maliciously constructed save files can harm your computer..." is a security feature introduced in Ren'Py 8.1 to protect users from potential exploits hidden in shared save files. Why This Happens

Ren'Py save files use the Python pickle format, which is highly flexible but can be used to execute arbitrary code on a computer if the file is maliciously modified.

New Security Layer: To prevent "spiked" save files from running unauthorized scripts, Ren'Py now tracks where a save was created.

Trigger: 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

Security: This provides a necessary warning for players who download "100% completion" saves from untrusted internet sources.

Minor Inconvenience: For users simply syncing progress between their own devices, this pop-up adds an extra step but is generally a one-time confirmation per save.

Potential Bugs: In some games with custom UIs, this prompt may appear as a blank screen if the developer hasn't updated their confirm screen to include the new security prompts (UNKNOWN_TOKEN and TRUST_TOKEN). Workarounds & Solutions

If you are confident the save file is safe (e.g., it is your own file), you can bypass or fix the warning using several methods:

Official Syncing: Use Ren'Py Sync, a built-in SDK feature that allows secure transfer of saves and persistent data via a 10-character code.

Manual Token Reset (Advanced): Users often fix this by navigating to their %appdata%/RenPy/tokens/ folder and editing the security_keys.txt file to remove specific strings under the signing and verifying keys, then setting the file to "read-only".

Engine Modification: For those with technical knowledge, modifying the Ren'Py engine file by replacing if token_dir is none: with if true: effectively disables this check.

This message is a crucial security feature in Ren’Py games that ensures your progress stays safe when moving between a PC, phone, or cloud storage. 🛡️ Why It Matters

Prevents Corruption: Stops data crashes from mismatched versions. Security Check: Confirms you intend to load external data.

Seamless Portability: Enables playing the same save on multiple platforms. ✅ The Good Crystal Clear: You know exactly why the prompt appeared.

One-Click Fix: Usually requires just one confirmation to proceed.

Reliable Protection: Safely links your progress across hardware. ⚠️ The Catch Repetitive: Can feel tedious if you swap devices often. False Alarms: Sometimes triggers after simple OS updates. Minor Friction: Breaks the "immersion" for a split second.

⭐ Verdict: It is a small, necessary "handshake" that keeps your hours of gameplay from disappearing into a glitchy void.

The message "This save was created on a different device" is part of the Save Token Security system introduced in Ren'Py 8.1. This security feature is designed to protect your computer from potentially malicious code, as Ren'Py save files use the "pickle" format, which can execute arbitrary code if a file is modified by a bad actor. How to Fix or Bypass the Message

Depending on your platform and how comfortable you are with technical steps, you can use several methods to resolve this: 1. Standard In-Game Prompt (Easiest)

In most modern Ren'Py games, you should see a prompt asking if you trust the device the save was created on.

Action: Select "Yes" to trust the save. Once loaded, re-save the game into a new slot on your current device. This will generate a new security token linked to your current machine, and the warning should disappear for that new save. 2. Modified security_keys.txt (For Android/PC)

If you are moving saves between mobile and PC, you can manually reset the security keys.

Locate the Folder: Find the folder where your game saves are stored. On Windows, this is usually in %APPDATA%/RenPy/[game_name]. On Android, it is within the game's internal data folder. Edit the File: Look for a file named security_keys.txt.

Reset Keys: Open it with a text editor and replace all existing text with only the word Signing-key.

Set to Read-Only: Save the file, right-click it, go to Properties, and check the Read-only box. Restart the game and try loading the save again. 3. Engine-Level Bypass (Advanced)

If you have access to the engine files themselves, you can disable the check entirely.

Find the Engine File: In the Ren'Py installation folder, find the file named renpy.

Modify Code: Open it and search for the line: if token_dir is none:.

Replace: Change that line to: if true:. This effectively disables the device verification check. 4. Using Ren'Py Sync

If the game developer has enabled it, use the official Ren'Py Sync service. renpy this save was created on a different device link

Upload: On the original device, select "Upload Sync" to get a 10-character code.

Download: On the new device, select "Download Sync" and enter that code to transfer both saves and persistent data securely. Why this happens

Ren'Py saves are not just data; they are "snapshots" of the game's Python state. Because this state can be manipulated, the engine now checks if the "token" (a unique ID for your device) matches the one in the save file. If it doesn't match, it triggers these security warnings to ensure you aren't loading a file from an untrusted source.

Are you trying to move a save from Android to PC, or are you seeing this while using a cloud service like Steam Cloud?

"This save was created on a different device" a security notification introduced in Ren'Py 8.1 as part of a new Save Token Security Why this message appears

Ren'Py now assigns a unique "token" to save files to identify the device that created them. If you try to load a save from a different computer or a modified save file (e.g., from a save editor), Ren'Py prompts you to confirm that you trust the source.

This warning is designed to prevent "maliciously constructed save files" from potentially harming your computer. How to resolve it Depending on whether you are a , here is how to handle this: For Players: Click "Yes":

If you manually transferred the save yourself or trust the person who gave it to you, click to continue loading the file. Blank Screen Issue:

If you see a blank screen instead of a "Yes/No" prompt, the game developer likely hasn't updated their UI to include the new security prompts. You may need to wait for a game update or manually disable the protection (see below). For Developers: Update your UI: Ensure your screens.rpy includes the gui.UNKNOWN_TOKEN gui.TRUST_TOKEN Disable Save Protection:

If you want to bypass this check during development, find the initialization file and replace the line if token_dir is none: Moving Saves Between Devices

If you want to move saves without encountering this error frequently, consider using the official Ren'Py Sync On the original device: "Upload Sync" in the game menu to get a 10-character code. On the new device: "Download Sync"

and enter the code to transfer your saves and persistent data. Ren'Py Sync

Not all games support Ren'Py Sync; it must be enabled by the developer using the Sync SDK. Ren'Py Sync Are you experiencing this message while playing a game developing one Ren'Py Sync

This is a common issue with games when moving save files between different operating systems or versions of the game engine. Why it happens Persistent Data Mismatch:

Ren'Py stores some information in a "persistent" file and other data in individual "save" files [2, 5]. If you move a save file but not the persistent data, the game sees a discrepancy in the engine version internal script headers Ren'Py Version Updates:

If the developer updated the game to a newer version of the Ren'Py engine between your two play sessions, the old save may be technically incompatible with the new engine's "pickling" (data saving) process [2, 4]. Steam Cloud Conflicts:

If playing via Steam, the cloud might have synced a save from a different OS (e.g., Mac to Windows), which occasionally causes pathing errors within the save metadata [3]. How to fix it Force Load: Most of the time, you can simply click

or "Proceed" when the warning pops up. Ren'Py is generally good at reconstructing the state, though you might see minor glitches or missing images for one or two frames [1, 4]. Sync Persistent Data: If you are manually moving files, ensure you copy the persistent file located in the /game/saves/ folder or the %APPDATA%/RenPy/ directory alongside your files [2, 5]. Check Game Version:

Ensure both "devices" are running the exact same version of the game. If one is an older build, the save headers won't match [4]. Are you trying to transfer a save between a PC and a phone, or did this happen after a game update

The notification "This save was created on a different device" is a security feature introduced in Ren'Py 8.1. It is part of the Save Token Security system designed to prevent "maliciously constructed" save files from harming your computer.

If you are transferring your own saves between devices, you can usually bypass this by simply selecting "Yes" to trust the save when prompted. If the screen is blank or the prompt doesn't appear, you may need to update your game's confirm screen code to support these new security prompts. How to Fix or Bypass the Security Warning

If you are a player encountering this issue, follow these steps based on your device: For PC (Windows/Mac/Linux):

Trust the Save: When the prompt appears, click "Yes" to trust the device the save was created on.

Transfer All Files: Ensure you copy both the files in the game/saves folder and the persistent data located in your system's AppData (Windows) or Library (Mac) folders to maintain full compatibility. For Android:

Manual Key Replacement: You can create a file named security_keys.txt containing only the text Signing-key.

Set this file to read-only, then transfer it to your device and replace the existing signing_keys.txt in the game's save folder.

Load the game, create a new save, then delete the file you created to resume normal operation. Official Syncing:

Use the Ren'Py Sync feature if the game supports it. Select "Upload Sync" on the original device to get a 10-character code, then use "Download Sync" on the new device to transfer data securely. Information for Developers

If you are developing a game and want to prevent this for your players or yourself:

Update Screens: Ensure your confirm screen includes prompts for gui.UNKNOWN_TOKEN and gui.TRUST_TOKEN.

Config Keys: You can add specific save tokens to config.save_token_keys to allow saves from known trusted sources without a prompt. The message " This save was created on a different device

Warning: Disabling this protection or trusting unknown save files from the internet can be a security risk, as save files can contain executable code.

Step 2: Try Loading the Save File on the Original Device

If possible, try loading the save file on the original device or platform where it was created. This can help you determine if the issue is device-specific.

Step 1: Locate the Ren'Py Registry or Persistent File

On the Original Device (where the saves work), navigate to the Ren’Py data folder.

  • Windows: %APPDATA%\RenPy\
  • macOS: ~/Library/RenPy/
  • Linux: ~/.renpy/
  • Android: Difficult (requires root or extracting the persistent file via ADB).

Inside this folder, look for a subfolder matching your Game Name (e.g., MyVisualNovel-1234567890).

1. Introduction

Ren’Py, the popular visual novel engine, includes built-in save encryption and device fingerprinting to prevent save file tampering or cross-device corruption. When a player tries to load a save file that was created on a different computer, Android device, or even a different operating system, Ren’Py may display:

“This save was created on a different device.”

This paper explains why this happens and how to bypass or fix it.

Permanent Fix for Developers

If you’re making a Ren’Py game and want saves to work across devices without warnings:

# In options.rpy or script.rpy
define config.use_save_token = False

This disables the device-locking mechanism entirely. Use this if:

  • Your game is single-player offline only
  • You explicitly want users to share saves
  • You’re building for platforms like Steam Deck + PC + Mac

⚠️ Warning: This does make saves more vulnerable to corruption or cheating.

What it means (short)

Ren'Py embeds device- or environment-specific metadata in save files (version, UUID, and sometimes absolute paths). If the runtime detects a mismatch it warns the player to avoid loading incompatible or corrupted saves.

Final Thoughts

The “different device” error is annoying but well-intentioned. With the newer [link] system, it’s no longer a dead-end. If your game doesn’t have the link, ask the developer to update to Ren’Py 8.2+ or 7.7+.

And if you’re a dev: decide whether you want security or freedom, and set config.use_save_token accordingly.

Title: Resolving the "Save Created on a Different Device" Issue in Ren'Py: A Comprehensive Analysis and Solution

Introduction

Ren'Py, an open-source visual novel engine, has been widely used by developers to create interactive stories and games. One common issue faced by Ren'Py developers and players is the "Save created on a different device" error. This error occurs when a player attempts to load a save file created on a different device, resulting in a failure to load the game. In this paper, we will analyze the causes of this issue, explore existing solutions, and provide a comprehensive guide to resolving this problem.

Causes of the Issue

The "Save created on a different device" error in Ren'Py is primarily caused by differences in the file paths and encryption keys used by the engine on various devices. When a player saves a game, Ren'Py generates a unique save file that contains the game's state and data. This save file is specific to the device it was created on and cannot be loaded on a different device due to differences in:

  1. File Paths: Different devices have varying file system structures, leading to distinct file paths. When a save file is created on one device, it contains file paths that may not exist on another device.
  2. Encryption Keys: Ren'Py uses encryption to protect save files. The encryption key used on one device may differ from the one used on another device, making it difficult to load the save file.

Existing Solutions

Several solutions have been proposed to address the "Save created on a different device" issue:

  1. Cloud Saving: One approach is to implement cloud saving, where save files are stored on a remote server, allowing players to access their saves from any device. However, this requires additional infrastructure and may introduce latency.
  2. Device-Specific Save Files: Another solution is to create device-specific save files. This involves generating a unique identifier for each device and storing it in the save file. When loading a save file, the game checks the device identifier to ensure it matches the current device.

Comprehensive Solution

To resolve the "Save created on a different device" issue, we propose a comprehensive solution that involves:

  1. Standardizing File Paths: Implement a standardized file path system that can be used across devices. This can be achieved by using relative file paths or a virtual file system.
  2. Encryption Key Management: Develop a system to manage encryption keys across devices. This can be done by generating a unique encryption key for each device and storing it securely.
  3. Save File Compatibility: Ensure that save files are compatible across devices by including device-specific information, such as the device identifier, in the save file.
  4. Automatic Save File Conversion: Implement an automatic conversion system that updates save files to be compatible with the current device.

Implementation in Ren'Py

To implement the proposed solution in Ren'Py, developers can use the following code:

# Standardize file paths
def get_save_directory():
    # Get the save directory path
    save_dir = os.path.join(os.path.expanduser("~"), "RenPy Saves")
    return save_dir
# Manage encryption keys
def generate_encryption_key():
    # Generate a unique encryption key
    encryption_key = secrets.token_hex(16)
    return encryption_key
def load_save_file(filename):
    # Load the save file
    save_file = os.path.join(get_save_directory(), filename)
    with open(save_file, "rb") as f:
        save_data = f.read()
    # Decrypt the save file
    encryption_key = generate_encryption_key()
    decrypted_save_data = decrypt(save_data, encryption_key)
    return decrypted_save_data
def save_game(filename):
    # Get the current device identifier
    device_id = get_device_id()
    # Create a new save file
    save_file = os.path.join(get_save_directory(), filename)
    # Encrypt the save file
    encryption_key = generate_encryption_key()
    encrypted_save_data = encrypt(save_data, encryption_key)
    with open(save_file, "wb") as f:
        f.write(encrypted_save_data)
# Automatic save file conversion
def convert_save_file(filename):
    # Load the save file
    save_data = load_save_file(filename)
    # Convert the save file to be compatible with the current device
    save_data = convert_save_data(save_data)
    # Save the converted save file
    save_game(filename)

Conclusion

In conclusion, the "Save created on a different device" issue in Ren'Py can be resolved by implementing a comprehensive solution that standardizes file paths, manages encryption keys, ensures save file compatibility, and provides automatic save file conversion. By following the proposed solution and implementation guide, developers can create a seamless gaming experience for players across different devices.

Future Work

Future research can focus on:

  1. Improving Cloud Saving: Developing more efficient cloud saving solutions that reduce latency and improve player experience.
  2. Enhancing Save File Security: Exploring more secure encryption methods and developing best practices for managing encryption keys.

By addressing the "Save created on a different device" issue, Ren'Py developers can create more engaging and immersive visual novels and games that can be enjoyed by players across various devices.

This message is part of a Save Token Security system introduced in Ren'Py 8.1. It is a security feature designed to protect your computer from malicious save files when you transfer progress from a different device. How to Resolve the Message When you see this prompt, you generally have two choices:

Trust the Save: If you created the save yourself on a different device or trust the creator, you can select "Yes" to proceed with loading.

Create a Fresh Save: To stop seeing the message for that specific progress, load the save (by clicking "Yes"), then immediately save the game again in a new slot. This generates a new security token linked to your current device. Why You Are Seeing It

Device Transfer: You moved a save file from one computer/phone to another.

Cloud Sync: You are using a cloud service (like Steam Cloud or a manual sync) that downloaded a save created on another machine.

Edited Saves: If you used an online save editor, the resulting file will lack the security token for your specific device. For Developers

If you are developing a game and this message appears as a blank screen or causes an error, your custom confirm screen might be missing the necessary logic to handle these specific prompts. You need to ensure your UI can display the UNKNOWN_TOKEN and TRUST_TOKEN messages. Linking Saves Across Devices

If you want to sync your saves officially without manual file moving, look for the Ren'Py Sync feature in the game's menu if the developer has enabled it:

On Device A: Go to the Save menu and select Upload Sync to get a 10-character code.

On Device B: Go to the Load menu, select Download Sync, and enter that code. Note: This sync typically only lasts for 24 hours.

Are you trying to manually move files between specific platforms, like Android to PC?

The "This save was created on a different device" link error typically occurs when you try to load a saved game in Ren'Py that was created on a different device or platform. This error is often accompanied by a warning message that indicates the save file is not compatible with the current device or platform.

The error message is usually displayed as:

This save was created on a different device. You may not be able to load it.

or

The save file you are trying to load was created on a different device. This may cause problems.

Causes of the Error

So, why does this error occur? There are several reasons:

  1. Different Device or Platform: The most common reason is that the save file was created on a different device or platform (e.g., from a Windows machine to a Mac or Linux).
  2. Incompatible Ren'Py Version: If the Ren'Py version used to create the save file is different from the one you're currently using, it may cause compatibility issues.

Resolving the Error: A Step-by-Step Guide

Don't worry; we've got you covered! Here are some steps to help you resolve the "This save was created on a different device" link error:

The Solution: Match the save ID

You need to edit the game script to force your current game to accept the ID of the save file.

  1. Find your Save ID:

    • If you still have the old device/game, open the options.rpy or gui.rpy file and look for a line starting with define config.save =.
    • If you do not have the old game, you can try opening the save file (it's often inside a .zip or .rpyc format, but you can open the save slot file using a text editor like Notepad++). Scroll through the garbled text; usually, the ID is visible as plain text near the top or bottom of the file structure.
    • Common default IDs look like: "MyGame-123456789" or just a long string of numbers/letters.

  2. Edit the New Game:

    • Go to the game folder on your new device.
    • Open options.rpy, gui.rpy, or create a new file called fix_save.rpy.
    • Add (or modify) the following line of code:
    define config.save = "THE_ID_YOU_FOUND_IN_STEP_1"
    • Example: If the old ID was solid_piece_987, the code should look like: define config.save = "solid_piece_987"

  3. Rebuild/Load:

    • If you are a developer, rebuild your game.
    • If you are a player, place this .rpy file inside the game folder of the installed game (alongside the other .rpy files). Ren'Py will read it on startup.
