There is a unique thrill in beating a difficult RPG fair and square. But there is a different, arguably more technical thrill in cracking open the game’s save file and rewriting reality itself.

If you have ever played a fan-made Pokémon game (like Pokémon Reborn, Insurgence, or Uranium) or any RPG Maker XP game, you have encountered the mysterious .rxdata file. Unlike standard .sav files, you can’t just open these in a hex editor and change your money to $999,999. Blog Title: Mastering the Save: A Guide to Editing

Today, we are diving into the underground art of the Save Editor RXData.

1. What is RXData?

RXData (.rxdata) is Ruby-serialized data used by RPG Maker (XP/VX/VX Ace) to store game database objects (maps, items, actors, etc.).

RPG Maker Version Differences

• RPG Maker XP → Standard .rxdata with Marshal.
• RPG Maker VX/VX Ace → Uses Marshal but object structures differ (e.g., $game_party has different attributes).
• RPG Maker MV/MZ → Uses JSON or encrypted .rmmzsave — not directly compatible with RXData editors.

Python Example (with rxdata module or custom loader)

import marshal
# Note: Python's marshal is not identical to Ruby's.
# Use rpgmaker-rxdata library or load as binary + manual parsing.

Better: Use Ruby via RGSS or standalone:

require 'objspace'
save = Marshal.load(File.binread("Save01.rxdata"))
save[5].hp = 9999  # index 5 is $game_actors array
File.binwrite("Save01_edited.rxdata", Marshal.dump(save))

You can even build a GUI with Shoes or GTK2 for non-programmers.

Problem 4: My changes revert after loading the save.

• Cause: The game stores a backup save in the same file. When it detects a mismatch, it restores the old data.
• Fix: Use the editor to also modify the backup block. In PokeGen, look for "Save Slots" and edit both Slot A and Slot B.
