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

[L33THAK0R]

Hi all,

Been trying to figure out how to go about compressing "Prey" (2017 release) (Incl. Mooncrash and Pre-Order Bonus DLC). I'm using the GOG release which according to users and the "Prey" .pak decryption tool, the .pak files are already decrypted. Using

xzlib+srep:m3f+4x4:b64mb:lzma:ultra:64m:bt4:fb273:lc8:mc1000000

I'm only able to get the title down 22.5GB, however other users smaller sizes are possible. Any help or advice would be greatly appreciated!

Telling the original size is much appreciated. He also used BPK which you didn't use. You never know what impact a particular compressor has on the size of the game.

My original size is 30.5gb, I didn't include the .bk2 videos as I plan to offer the end-user a choice between the original and encoded videos. All .bk2 videos result in a grand total of 1.46gb (uncompressed) so I don't think (though I may be wrong) my lack of BPK is an issue, unless of course there are additional video files within the .pak container files.

As I said, you never know. I see only two options now:

1. Try again using bpk and see the results.
2. Or you can scan the game for various streams and create algorithm based on it.

Can you show your arc.ini?

My arc.ini is here. Thank you for offering to take a look at it, any help or advice means a lot to me! I should mention I've been using Tiny Compressor 1.4 to put together my conversions, as I'm not comfortable enough with my knowledge of this field to try out more feature packed alternatives such as DiskSpan.

Don't worry because at first, i too was afraid to use DiskSpan. Since i was using UltraArc and it had less options but you have to try different things to learn and life is all about experiment ain't it?

I suppose so, I've managed to add any compressors I've needed to my tiny compressor installs so far, and I haven't encountered any issues other than making sure my options/arguments/commands for the compressor in question are correct. My only limitation currently is the available compressor to choose to include in my setup.exe, as I'm using ASIS v7.2.0 (newer versions are giving me a hard time), but I'm confident in time I'll be able to add the appropriate additional decompression executables (not sure if that's the right term) when I'm required to (i.e. oodle compressors, and Razor's title specific tools).

Give LIS a shot, its pretty clean and has most of the newer compressors.
I would also recommend the Razor's WPI Installer, you can modified it according to your liking.

The CorePack Script by BlackFire69 also has option to import custom compressors in it + it looks badass too.
It's the only reason I use diskspan because many iss scripts are made specifically for it like LIS, ASIS, and CIU v3.

I think asis loads a setup.dll, an arc archive which has external compressors. You can study that and create your own setup.dll for your setup.exe.

I went down this route and even had some very kind users here offer their skills and help but alas I ended up sticking with v7.2.0.

I am a newbie myself and I will say diskspan_gui is very easy to use

It's probably a placebo but I've found any large (5gb+) conversion with DiskSpan to take significantly longer compared to the same operation using Tiny Compressor. I'm not sure if the disk output sizes of DiskSpan change the length of the compression so could also be my lack of knowledge. I also prefer manually editing the "custom" input for tiny compressor in the arc.ini file but I'm a bit of an autistic **** honestly.
