Subformats
Ascendancy has a number of proprietary formats in the COB file. All of the non-audiovisual stuff is stored as CSV. Some formats are defined below:
RAW
Raw, 22050Hz PCM audio. (I'll look up endianness and other details ASAP)
VOC
Creative VOiCE files [1].
SHP
Ship visuals. All little-endian Main file header:
Offset Size Value 0x00 4 bytes Magic number: 0x30312E31 0x04 4 bytes Number of ship images in file 0x08 4 bytes Offset into file of color palette for ship 1 0x0C 4 bytes Offset into file of image for ship 1 0x10 4 bytes Offset into file of color palette for ship 2 0x14 4 bytes Offset into file of image for ship 2
