Best Compression Methods for 'Specific' Games. Q&A

[Masquerade]

*.SPK from Steelrising are just zip files with what appears to be no compression. I cannot speak for the larger packs but the locales zips have data just stored.

Compressing datapc_initial.spk

Compressed 1 file, 10,852,967,682 => 18,870,379,505 bytes. Ratio 173.87%
Compression time: cpu 9.08 sec/real 215.30 sec = 4%. Speed 50.41 mB/s
All OK

Files compressed zlib inside SPK

All SPK
66.5 gb > 116 gb.

Question.
datapchighres.spk - is optional data or not?

Nope, game is made in same engine as Greedfall. The file datapchighres.spk is basically the whole game data.

Really? After all, the game works fine without these files. Especially on weak systems like mine

Really? I did not expect that. If you rip the highres file in Greedfall the game becomes unplayable

In this cases I always look on steamdb for optional depots.
If no info is provided then just rename the files/folders and play a bit and see if it works.

Have more tips, hints in recompress the old gamez, named in Space Empires V Hungarian Edition contains ~1GB's BMP files and 110+ MB's JPG files with WinXP compatibility setups. Use MSC this compression? Or any methods in better? Total game size: ~1.44GB

for bmp files use MSC or Internal Compressor (GRzip) and for jpg files use packjpg

Where do I need to get this GRZip? It would be helpful if you posted this tool here for compression testing to use.

Isn't LOLZ better to use?

[kj911]

Caldric: This GRZIP compression algo its internally available from FreeArc! Use -mbmp switch from have compressing.

LOLZ its probably better. Quickly tested ~85MB's BMP files portion its 1GB's filepackage, from compare the compression. (x86 only compressors.)

Best: MSC+DLZ (better than MSC+LZMA combo.)
Default LZMA only its better than MSC packed one.*

*with 10-20% ratio from full input data, not packed in BMF. This MSC integrated BMF, not 100%-ish processing these bmp files within unsupported resolution issues.

LOLZ its testing in next days.

JPG compression:

My pretest in ~113MB's JPG files packing, get best results: "precomp043+srep:m3f:l32+lzp:3:16mb:h22" or replace precomp old to newest 0.4.8 version. This Precomp 0.4.8 (from KPS) ~4* faster in compression than released by profrager this v0.4.3 CLS-version.

As kj911 said (GRzip) is a built-in compressor in FreeArc

It's a zip file with no compression but encrypted. Currently looking into it.

What is NBA2k23 using? Can't find any samples yet and don't want to download 122gb just for testing.
