File Format

Header

Offset (+Hex)	Type	Name	Information
0000	dword	version	Version numbers: 0x2711 - New movies 0x2710 - Old movies
0004	dword	columns	The number of columns.
0008	dword	rows	The number of rows.
000C	dword	delayrate	Sound playback rate, in 1/100 sec per frame.

If the version is 0x2711 then this section comes right after the header.

Offset (+Hex)	Type	Name	Information
0000	dword	sounds	The number of sounds in the file.
0004	char[sounds][50]	sound_files	The filenames of each sound that can be played during the movie. Filenames are null-terminated and padded to 50 bytes; the game itself will look for "data\sound\[filename].ogg".
*	dword[200][16]	sound_time	Sound IDs to play during the first 200 "sound ticks" (as per the "delayrate" specified above). Up to 16 sounds can be played during each frame.

The Sounds section & Header section comes before this. The remainder of the file is made up this way.

Offset (+Hex)	Type	Name	Information
0000	dword	size	The size of the following compressed data.
0004	byte[size]	data	Zlib's deflate compressed data, comprising no more than 200 sequential frames.

Offset (+Hex)	Type	Name	Information
0000	char[Header.columns * Header.rows]	characters	The characters making up the frame.
*	attribute[Header.columns * Header.rows]	attributes	The color attributes of each character in the frame.

Or: Index = X * Header.rows + Y

A frame is a single byte long, the bits are layed out as:

0ibbbfff
i   - Foreground Intensity Bit
bbb - Background Color Bits
fff - Foreground Color Bits
