This is the format for resources of type STRTAB. It contains a number of
|
|
items of unspecified data (not necessarilly strings).
|
|
This is used for game strings (extension .txt), colour tables (.ct),
|
|
colour translation tables (.xlt), and sound-effect tables (.snd)
|
|
|
|
Everything is stored MSB first unless otherwise specified.
|
|
|
|
position length meaning
|
|
4 0xffffffff if the file is uncompressed.
|
|
Otherwise, the file is compressed. When uncompressed, the
|
|
file complies with the rest of the format as described
|
|
below.
|
|
2 Unused in file, always 0x0000
|
|
2 number of items in the file (StringCount)
|
|
|
|
Followed by:
|
|
In file:
|
|
4 Placeholder, always 0x00000000
|
|
numitems times:
|
|
4 length of string
|
|
In memory:
|
|
numitems times:
|
|
4 offset from &StringCount to the string
|
|
followed by:
|
|
4 offset from &StringCount until one char past the end
|
|
of the last string.
|
|
|
|
For .ct files an item is as follows (new 256x24bit format):
|
|
1 Index of first clut in this item.
|
|
1 Index of last clut in this item.
|
|
For each clut:
|
|
256 palette entries:
|
|
1 red value
|
|
1 green value
|
|
1 blue value
|
|
|
|
For old .ct files an item is as follows (obsoleted by new 256x24bit format):
|
|
1 Index of first clut in this item.
|
|
1 Index of last clut in this item.
|
|
For each clut:
|
|
32 palette entries:
|
|
2 bits 0-4: blue value
|
|
bits 5-9: green value
|
|
bits 10-14: red value
|
|
bit 15: specifies the interpolation mode for 3DO scaling
|
|
(is ignored now)
|
|
The full palette contains 256 values, which are the original 32 values
|
|
multiplied by 1 to 8.
|
|
|
|
|
|
For .ct files (planet surface version; in ipanims) an item is as follows:
|
|
1 Index of first color in this colortab.
|
|
1 Index of last color in this colortab.
|
|
Then for each color (6 bits per channel):
|
|
1 bits 0-5: red value
|
|
1 bits 0-5: green value
|
|
1 bits 0-5: blue value
|
|
The planet surface palette files were probably copied verbatim from DOS version
|
|
and left alone because they do no exactly fit into the whole CLUT system.
|
|
|
|
For .xlt files (planet surface; in ipanims) an item is as follows:
|
|
2*3 3 elevation levels (not used, probably informational)
|
|
1*256 256 colormap indices each corresponding to a particular
|
|
elevation level 0..255; only colormap indices 128..255
|
|
can be used currently because colormaps only define
|
|
colors 128..255
|
|
The .xlt files combined with planet surface .ct files are used to select colors
|
|
for planet surface rendering.
|
|
|
|
|
|
For .snd files an item is as follows:
|
|
N-2 Signed, 8-bit, 1 channel PCM samples of the sound
|
|
effect, where N = (length of string)
|
|
2 Sampling frequency of the sound, *LSB first*
|
|
(the frequencies themselves seem to be remnants of
|
|
the DOS version)
