Compatibility

Support by generation

The same RPG Maker name covers several unrelated save generations. SaveEditor.com keeps those formats separate so a detected extension is never mistaken for verified write support.

Generation	Typical file	Standard storage	Read	Write
RPG Maker MZ	`.rmmzsave`	JsonEx + zlib/DEFLATE	Verified	Verified
RPG Maker MV	`.rpgsave`	JsonEx + LZ-String Base64	Verified	Verified
RPG Maker VX Ace	`.rvdata2`	Ruby Marshal 4.8	Verified bounded	Verified bounded
RPG Maker VX	`.rvdata`	Ruby Marshal 4.8	Verified bounded	Verified bounded
RPG Maker XP	`.rxdata`	Ruby Marshal 4.8	Verified bounded	Verified bounded
RPG Maker 2000 / 2003	`.lsd`	Legacy binary family	Candidate detection	Not supported

Plugin-modified saves: an MV or MZ game can replace or extend the default serialization. A matching extension alone does not guarantee compatibility.

Operational catalog

Verified RPG Maker tools

Only records with a Verified support state, an Operational runtime, and the tested rpgmaker-v1 or rpgmaker-v2 engine appear here. Phase 33 reaches 25 operational RPG Maker surfaces without claiming RPG Maker 2000/2003 support.

Edit scope

What the generic editor changes

The engine edits only fixture-backed fields whose serialized location and type are proven for the selected generation. It deliberately avoids progression data and arbitrary project logic that can depend on scripts, plugins, or game-specific rules.

Party gold

Bounded standard party gold value.

Switches

Boolean switch state by numeric database ID.

Variables

Finite scalar values by numeric variable ID.

Inventory

Item, weapon, and armor quantities by database ID.

Actor identity

Saved actor name and nickname only.

Not generic

Level, EXP, classes, skills, derived stats, plugin objects, and project database definitions.

Workflow

Edit the copy, not the original

A structurally valid output can still conflict with game-specific plugin logic. Keep the source save untouched until the edited copy loads and behaves correctly in the original game.

01Back up
Copy the original save to a separate location.
02Detect
Confirm that the file is a supported MV/MZ save or a verified XP/VX/VX Ace Ruby Marshal workflow.
03Edit minimally
Change only the field required for the task.
04Download a new file
The working copy is re-encoded into its original supported generation.
05Test before replace
Load the edited copy in the original game before removing the backup.

Format transparency

Why each RPG Maker generation is treated separately

Standard MV and MZ both serialize save contents as JsonEx data, but their local storage codecs differ. The browser engine therefore uses separate verified decode/encode paths instead of assuming that every RPG Maker save is interchangeable.

XP, VX, and VX Ace use Ruby Marshal-family data and are handled only through the bounded Phase 33 structural parser/serializer where class shapes are fixture-backed. RPG Maker 2000/2003 uses a different legacy save family and remains unsupported.

FAQ

RPG Maker save support

These answers describe the verified generic engine. Individual games can still add custom save behavior through plugins.

Can SaveEditor.com edit RPG Maker MV saves?

Yes, for standard MV .rpgsave files that use the normal JsonEx plus LZ-String Base64 storage path. Plugin-defined codecs can be incompatible.

Can it edit RPG Maker MZ saves?

Yes, for standard MZ .rmmzsave files using the normal JsonEx plus zlib/DEFLATE StorageManager path and a browser with the required Compression Streams support.

Can it edit VX Ace, VX, or XP saves?

Yes, within the narrow Phase 33 boundary: supported .rvdata2, .rvdata, and .rxdata files must parse as bounded Ruby Marshal 4.8 and expose the fixture-backed RPG Maker class/instance-variable shapes required by the selected tool. Custom scripts or unsupported Marshal structures fail closed.

Does the inventory editor know item names?

No. The save contains inventory maps keyed by database ID, while item names live in the project database. The generic editor therefore uses numeric IDs and does not guess labels.

Does a successful validation mean the game will accept the save?

No. Validation confirms the supported codec and expected serialized structure. Game-specific plugin logic, version changes, or custom checks can still reject an otherwise readable save.
