It consists of several key-value pairs followed by an inputlog section.
The inputlog section can be identified by its starting with a | (pipe).
The inputlog section terminates at eof.
Newlines may be \r\n or \n
Key-value pairs consist of a key identifier, followed by a space separator, followed by the value text.
Value text is always terminated by a newline, which the value text will not include.
The value text is parsed differently depending on the type of the key.
The key-value pairs may be in any order, except that the first key must be version.
Integer keys (also used for booleans, with a 1 or 0) will have a value that is a simple integer not to exceed 32bits
- version (required) - the version of the movie file format; for now it is always 3
- emuVersion (required) - the version of the emulator used to produce the movie
- rerecordCount (optional) - the rerecord count
- palFlag (bool) (optional) - true if the movie uses pal timing
- fourscore (bool) (*note C) - true if a fourscore was used
- port0, port1 (*note C) - indicates the types of input devices. Supported values are:
SI_GAMEPAD = 1,
SI_ZAPPER = 2
- port2 (required) - indicates the type of the FCExp port device which was attached. Supported values are:
SIFC_NONE = 0
String keys have values that consist of the remainder of the key-value pair line. As a consequence, string values cannot contain newlines.
- romFilename (required) - the name of the file used to record the movie
- comment (optional) - simply a memo.
by convention, the first token in the comment value is the subject of the comment.
by convention, subsequent comments with the same subject will have their ordering preserved and may be used to approximate multiline comments.
by convention, the author of the movie should be stored in comment(s) with a subject of: author
Hex string keys (used for binary blobs) will have a value that is like 0x0123456789ABCDEF...
- romChecksum (required) - the MD5 hash of the rom which was used to record the movie
- savestate (optional) - a fcs savestate blob, in case a movie was recorded from savestate
GUID keys have a value which is in the standard guid format: 452DE2C3-EF43-2FA9-77AC-0677FC51543B
- guid (required) a unique identifier for a movie, generated when the movie is created, which is used when loading a savestate to make sure it belongs to the current movie.
The inputlog section consists of lines beginning and ending with a | (pipe).
The fields are as follows, except as noted in note C.
|c|port0|port1|port2|
field c is a variable length decimal integer which is a bitfield corresponding to miscellaneous input states which are valid at the start of the frame.
Current values for this are
MOVIECMD_RESET = 1
the format of port0, port1, port2 depends on which types of devices were attached.
SI_GAMEPAD:
the field consists of eight characters which constitute a bitfield.
