This is a tool for editing RPGMaker save files. It currently supports save files written by RPG Maker MZ (.rmmzsave), but support for other versions of RPGMaker is planned for the future.
It uses Node.js for the backend and Electron for the GUI, which means you can interact with it using npm.
git clone https://github.com/nathan-b/rmse
npm install
npm start
You can load a save file into RMSE either by dragging and dropping from your file browser or by clicking on the friendly green box and selecting your save file from the resulting dialog box.
Hopefully the interface is fairly straightforward.
Each section can be collapsed or expanded by clicking on it.
Edited values do not take effect until you click one of the save buttons.
The inventory sections (items, armor, weapons) only show the current contents of your inventory. If you would like to add a new item that you currently don't have, you can use the dropdown box below each section to choose an item to add. Selecting an item and then clicking the 'Add' button will add that item to your inventory with a quantity of 1. You can then increase the quantity further if you would like.
If an inventory section does not show up, this is because your party currently does not have any of that type of inventory.
You can currently only edit characters who are in your active party. The ability to edit characters not currently in your party is a possible future enhancement. Let me know if this functionality would be useful, and that might inspire me to work on it :).
Note that for most games, the given character attributes are additive on top of what the character's attributes already are based on their current level. This means that the values you see in RMSE will not match the values you see inside the game. This is normal and expected.
Not all games use every character attribute, but the save files still include these attributes. Do not be alarmed if you see an attribute your game does not use. All is fine. Remain calm.
Variables are internal values and switches used by the game and are not normally exposed to the user. As a result, they can sometimes have strange or uninteligible names. Be aware that messing with values inside the variables section has a fairly high likelihood of messing up your save in some way. Use with caution, and maintain backups.
You can either overwrite the file you just loaded or save the file under a new name. For backup purposes, it's a good idea to create a new file when you're first editing, in case something goes wrong.
RMSE can both save and load the raw JSON values used by the save file. This functionality will probably not be useful to you, but it might under a few circumstances:
- Your game uses a custom plugin that RMSE doesn't read, and you want to edit those values.
- You want to edit something that RMSE doesn't load (such as characters not in the active party).
- You wish to explore the save file or edit it by hand, and you just need RMSE to unpack the save file for you.
Once you have dumped the raw JSON and then edited it, you can open the file using the normal way (by dropping it or selecting it) and load it back into RMSE. At that point, use Save as... to save it as a new (or existing) save file inside your game directory.
NOTE: For technical reasons, you can't save the file outside the game's directory. RMSE needs to use the game directory to figure out how to save the file. However, if you don't want to save the file in the saves directory, you can save it somewhere else inside the game directory. This restriction does not apply to JSON files, which can be saved wherever you please.
