GitHub hosts various community-made tools written in Python or Ruby (such as rvdata2 or rxdata decoders).
If using an online editor, drag and drop Save1.rxdata into the upload zone. If using a desktop application, open the software and use the "File > Open" menu to target your save. Step 3: Identify and Edit Key Variables
Once you are comfortable with simple edits, explore these advanced features unique to Rxdata manipulation.
Let’s assume you’re using a desktop editor like "RPG Maker XP Save Editor".
This cannot be overstated: . Corruption is a real risk, especially when using unofficial tools that may not fully understand the data structure of your specific game. A 40+ hour save file can become unreadable in an instant. Store your backup somewhere separate from the original — a different folder, an external drive, or even a cloud storage service.
⚠️ Over-editing (e.g., setting level 9999 in a game capped at 99) can crash the game. Always keep a backup.
Open your chosen tool (e.g., SaveEditOnline or a dedicated save manager) and load the .rxdata file. 4. Modify the Data
As suggested in this tutorial, try to save your game in a stable location (like a Pokémon Center) before editing. Conclusion
data = nil File.open("Data/System.rxdata", "rb") # use `data` in your script
Click File > Save . Overwrite the original .rxdata file in the emulator’s Battery folder. Close the editor.
