Compressed wad format:
|
|
|
|
Just like a normal wad, except:
|
|
|
|
1. The header id at the very beginning says "ZWAD"
|
|
instead of PWAD or IWAD.
|
|
|
|
2. The first four bytes of each lump are (little
|
|
endian) the uncompressed size. If this is zero,
|
|
the lump is not compressed, and you can subtract
|
|
four from the size given in the wadfile directory.
|
|
|
|
3. Unless those first four bytes give a value of
|
|
0, the lump is compressed with liblzf after that.
|
|
|
|
|
|
|
|
To compile this program, just compiling all its
|
|
source files should work, that is:
|
|
gcc *.c -o wadzip
|
|
|
|
[On a big-endian CPU, add "-DWORDS_BIGENDIAN" to
|
|
that command line.]
|
|
|
|
Visual C++ should also work, as well as gcc.
|
|
|
|
Compress a wad:
|
|
wadzip c original.wad compressed.wad
|
|
Decompress a wad (restoring the original):
|
|
wadzip d compressed.wad original.wad
