Yakuza 0 - Some Tests

.usm files when extracted, have no audio tracks to rip.
.cpk files when extracted, useless because it spawns 20,000 files of 20-50 KB's.
.Contains no streams at all, so you don't need to use a precompressor.

Overall, you can't rip anything out with the modding tools.

Most of you guys might have known about this but i still wanted to share it.

Edit : Upon testing, here are the results. GFS didn't detected any streams though.

precomp_mtx :
Compressed 4 files, 75,380,736 => 84,305,014 bytes. Ratio 111.84%
Compression time: cpu 0.11 sec/real 5.13 sec = 2%. Speed 14.69 mB/s
All OK

ZTool : Compressed 4 files, 75,380,736 => 84,394,635 bytes. Ratio 111.96%
Compression time: cpu 0.17 sec/real 14.04 sec = 1%. Speed 5.37 mB/s
All OK

Reflate : Compressed 4 files, 75,380,736 => 84,426,712 bytes. Ratio 112.00%
Compression time: cpu 0.11 sec/real 3.77 sec = 3%. Speed 19.98 mB/s
All OK

Preflate : Compressed 4 files, 75,380,736 => 84,480,615 bytes. Ratio 112.07%
Compression time: cpu 0.11 sec/real 4.35 sec = 3%. Speed 17.34 mB/s
All OK

Edit 2 : Nevermind, don't use a precompressor, i.e because i think only the one or two of above files contained streams and other files are either .usm or pck and some other extensions.
