RPG Maker formats / Format hub
RPG Maker MV Save JSON tools & compatibility
RPG Maker MV save JSON handled only through the verified MV profile and shared RPG Maker validation boundaries.
01 / Format context
Confirm the container and the profile.
SaveEditor separates wrapper recognition from semantic compatibility. Before processing a file, confirm the game or emulator, platform, version, expected size, and integrity rules described by the Tool itself.
Choose only a Tool whose support notes name the same format/profile.
File-size, encryption, signing, account, and browser-local limits still apply.
02 / Active tools
RPG Maker MV Save JSON tools with explicit support state
Planned and deprecated Tool records are excluded. Phase 43 cannot make an existing Tool verified or operational.
