Riven MLST resources
Movie lists: they specify the movies to be used in the card and their placement.
Each MLST resource is a list of records; it starts with an unsigned short record count, followed by that many records. This is the record structure:
|unsigned short||index||index of the record (starting at 1)|
|unsigned short||movie_id||Resource ID of the corresponding tMOV movie|
|unsigned short||code||Used by script commands to reference the movie record|
|unsigned short||left||Movie position within the game window (pixels)|
|unsigned short||loop||0 or 1, 1 means the movie must loop forever|
|unsigned short||volume||Volume of the movie sound track (details still unknown)|
As for unknown fields: u0 seems always 0000 0000 ffff and u1 seems always 1. Changing them produces no observable effects.
