Save States (v1.7.4 and later)

When a state is downloaded from the server, the state (savestate.state), screenshot (screenshot.jpg), and a json file (rominfo.json) describing the save state are zipped and downloaded.

The json file description is defined as follows:

{
  "Name": "Super Mario Bros. (1985-09-13)(Nintendo)(JP-US).zip",
  "StateDateTime": "2024-06-24T05:34:38",
  "StateName": "",
  "MD5": "7d158dcd242e77ba249ac8342474aa77",
  "SHA1": "3d4b04dc78f9d998f17d9fe9ad982a83b5ed72df",
  "Type": "ROM"
}

Attribute	Value
Name	The name of the ROM that the state belongs to. This is merely a convenience attribute.
StateDateTime	The date and time (in UTC) when the state was initially saved.
StateName	The name of the state
MD5	The MD5 hash of the ROM that the state belongs to.
SHA1	The SHA1 hash of the ROM that the state belongs to.
Type	Whether the state belongs to a ROM or ROM Group

If the zip is re-uploaded, the above json file will be used to automatically match the saved state to the ROM that created it.

If a zip is uploaded without the above three files, the upload will fail.

If a file is uploaded that is not a zip, it will be stored against the currently running ROM and a warning will be displayed that Gaseous was unable to verify that the state belongs to the ROM, and may not function as expected.
