03 / Read the status first
A tool name is not a compatibility guarantee.
Game save formats can change between platforms, game versions, storefronts, or updates. A SaveEditor.com tool page should state the input format it accepts, supported versions where known, its processing mode, limitations, and the date its support was last verified.
Verified means the tool has reached the project's supported state. In development means the record may be useful for documentation or progress visibility, but the interface must not be presented as finished. Planned and deprecated records stay out of the normal directory.
