File Format[edit]
Header[edit]
| 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. |
Sounds[edit]
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. |
Chunk[edit]
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. |
Data Format[edit]
Frame[edit]
| 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. |
Iterate through the frame data:
+---------> +Y | | | | V +X
Or: Index = X * Header.rows + Y
Attribute[edit]
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
