• PAL Files
• PLTT Resources (PLT 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 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.
