Here’s a clear breakdown:

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

While Ren'Py games try to accommodate cross-device compatibility, architecture differences can stall your progress. Here is a comprehensive guide on why this happens and how to sync your Ren'Py saves safely across multiple devices. Why Does Ren'Py Show This Warning?
