pak oo2reck + xtool reflate

bk2 files are KB2n, so bpk has no effect here.

Here are some tests (I have splitted the pak into 50mb parts for faster testing)

Code:

oodle 8 library
Compressed 1 file, 52,428,800 => 78,163,078 bytes. Ratio 149.08%
Compression time: cpu 0.16 sec/real 51.14 sec = 0%. Speed 1.03 mB/s
All OK

+ reflate
Compressed 1 file, 52,428,800 => 87,504,892 bytes. Ratio 166.90%
Compression time: cpu 0.08 sec/real 51.14 sec = 0%. Speed 1.03 mB/s
All OK

Extracted 1 file, 87,504,892 => 52,428,800 bytes. Ratio 166.90%
Extraction time: cpu 0.13 sec/real 3.77 sec = 3%. Speed 13.92 mB/s
All OK

Oodle 7 + 9 libraries gives worse ratio, so the way to go is 8.

Here are some other tests with oo2reck

Code:

xtool:reflate+oo2reck
Compressed 1 file, 52,428,800 => 87,730,149 bytes. Ratio 167.33%
Compression time: cpu 0.05 sec/real 67.07 sec = 0%. Speed 0.78 mB/s
All OK

oo2reck+xtool:reflate
Compressed 1 file, 52,428,800 => 88,079,648 bytes. Ratio 168.00%
Compression time: cpu 0.08 sec/real 68.80 sec = 0%. Speed 0.76 mB/s
All OK

Extracted 1 file, 88,079,648 => 52,428,800 bytes. Ratio 168.00%
Extraction time: cpu 0.08 sec/real 3.27 sec = 2%. Speed 16.02 mB/s
All OK

PS: If you want to make a database use "unreal_tournament_4_0.4.27c_paks_only.bms"

Thanks for the test, I can back you up here that XTool gives better ratio + speed boost than oo2reck (only minor though).

To be honest, there is no point in repacking at all. The difference is 1.5 GB and the installation takes almost 10 minutes. Such a pleasure

*.pak

xtool:mzlib+kraken + srep + lolz
```
*.bk2

Everything else:

Bink videos have KB2n header so no BPK support here.
