Game-specific containers / Format hub
Vampire Survivors Legacy JSON Save tools & compatibility
The explicitly legacy 2022 Vampire Survivors JSON family supported by the verified editor. Newer save families are not silently promoted.
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
Vampire Survivors Legacy JSON Save tools with explicit support state
Planned and deprecated Tool records are excluded. Phase 43 cannot make an existing Tool verified or operational.
