AoH2 Save Editor (Desktop)

A free, open-source save editor for Age of History II (also known as Age of Civilizations II). It opens the game's save files — which are stored in a binary Java format you can't edit by hand — and shows them as a readable, editable tree: money, civilization names, province ownership, diplomacy, technology, and everything else the game stores.

Prefer not to install anything? There's a browser version that does the same thing (nothing to download, works on any device): [placeholder]

What you can do

• Add money — set your civilization's treasury to anything.
• Rename civilizations — edit the name and tag (long and non-Latin names, e.g. Cyrillic, work fine).
• Transfer provinces / annex a country — change who owns a province, or use Batch Edit to move every province of one civ to another in a single click.
• End stuck wars — when the game won't let you make peace, edit the relationship value that drives the war.
• Edit anything else — technology, research, diplomacy points, population, and any other value the game wrote.

Download

Grab AoH2SaveEditor.exe from the latest release (Windows). It's a single portable program — no installer.

Windows SmartScreen may warn about an unrecognized app (normal for small, unsigned indie tools). Choose More info → Run anyway, or build it yourself from source (below).

How to use

1. Save in-game, then fully exit Age of History II.
2. Open the editor → File → Open Project Folder → select your save folder, usually: …\steamapps\common\Age of Civilizations II\saves\games\<map>\<your save>\
3. Use the Filter box (tag like ser2, or field=value like iTrueOwnerOfProvince=1) and double-click values to edit. Use Batch Edit to change many objects at once.
4. File → Save Modified Files (automatic timestamped backups are kept in a separate folder).
5. Load the save in-game.

Run from source (instead of the exe)

Requires Python 3.12+.

pip install javaobj-py3
python aoh2_editor.py

Build the exe yourself

build.bat

Produces dist\AoH2SaveEditor.exe.

Safety

The editor never overwrites your originals without keeping a timestamped backup, and it only writes when you choose Save. Still, keep your own backup of a save folder before editing, as with any save tool.
