RPG Maker MZ Save Editor

RPG Maker MZ saves keep the full state of a run in .rmmzsave files. Upload one to search the tree and change gold, stats, items or any switch the game set.

How to edit a RPG Maker MZ save

1. Open the game folder and go to save.
2. Upload the numbered file for your slot, for example file1.rmmzsave.
3. Find the value by searching for the number you see in-game.
4. Edit it, download, and replace the original file.

What you can change

• Gold and item quantities
• Actor levels, EXP and parameters
• Switches and variables driving quests and events
• Playtime and map position

Where the saves are stored

MZ keeps saves in a save folder inside the game directory — no www folder, unlike MV. Deployed browser builds again keep the state in local storage instead of on disk.

What the format actually is

MZ writes the same shape of data as MV — party, actors, switches and variables, with gold on the party as _gold — but compresses it with zlib rather than LZString. So the structure inside is familiar while the file itself is encoded differently, which is why tools written only for MV choke on it.

Questions

How is MZ different from MV?

Three things: MZ dropped the www folder MV used, so saves sit in a save folder directly inside the game directory; the extension changed from .rpgsave to .rmmzsave; and the file is zlib-compressed where MV used LZString. What is inside — party, actors, switches, variables — is structured the same way.

Can I open an MV save here instead?

Nothing stops you uploading either one — detection reads the file, not the name. Whether the game accepts an edited save from a different engine version is a separate question, and generally it will not.

What is global.rmmzsave for?

global.rmmzsave lists the slots and their timestamps rather than holding progress. If a slot has gone missing from the title screen, that is the file to look at.
