Movies and images are in a custom "SIFF" format (IFF-based, big endian).
GOB files
GOB files on the CDs have a TOC at the end of the file. Last 4 bytes are the number of entries in the table, each entry is 20 bytes in size, little endian:
0-12 filename null padded 13-16 offset 17-20 size
Python script to print out the TOC
from struct import unpack
from sys import argv
f = open(argv[1], 'rb')
f.seek(-4, 2)
num_entries, = unpack('<I', f.read(4))
f.seek((num_entries * -0x14) - 4, 1)
for _ in range(num_entries):
fname, off, flen = unpack('<12sII', f.read(0x14))
pos = f.tell()
fname = fname.decode("ascii").strip("\0")
print(f'{off:08x}\t{flen:08x}\t{fname}')
_ = f.seek(pos)
Files
File extensions and their internal type:
1-49 HOTB FCP FCPK PAN/PIM PXAN SON SOUN SPR PXAN
NTPD.ENC is "encrypted" using Caesar shift -5 (excluding \n !"#$&'(),-./?)
File listings of CD1.GOB and CD1MOV.GOB.
Misc
- Philip Mitchell is credited as the lead CD-i programmer but a CD-i version wasn't released
CDSTART.EXEis a Win16 Director 5 projector, but it is empty, so does nothing when ran
