Palette Files
PAL Files
PAL files are 768 bytes long, and store a single 256 colors palette as 256 x 3 RGB bytes.
Each level in Dark Forces can have its own palette, specified in the LEV header.
PAL_File IS
{
Colors RGB_Color[256] // 256 colors from 0 to 255
}Where:
RGB_Color Is
{
R byte // Red intensity
G byte // Green intensity
B byte // Blue intensity
}Note The intensities range from 0 to 63 (limit of VGA mode 0x13) in the PAL files.
PLTT Resources (PLT Files)
PLTT LFD resources are of variable size, and store a (possibly incomplete) palette used by ANIM and DELT resources.
Note The .plt extension is a convention adopted by add-on developers when writing conversion programs, there are no real PLT files in DARK FORCES.
PLTT_File IS
{
First byte // first color in the palette
Last byte // last color in the palette
colors RGB_Color[n] // n = Last - First + 1
pad1 byte // unused = 0
}Where:
RGB_Color Is
{
R byte // Red intensity
G byte // Green intensity
B byte // Blue intensity
}Note Contrary to the PAL files, the intensities range from 0 to 255 in the PLTT resources.
