CorePack Compression methods ? Help

[panker1992]

Srep can indirectly show if delta is good or not, anything srep's ratio can go below 70 or 65% then delta helps.

dont forget that srep delta and lzma are all based on lz77 matchfinding architecture

At last, someone with knowledge worth to talk...Haha..

You hope to replace every reoccurrence firstly and then again try to do so and hope it will be smaller...LOL...It's Common Sense of Humanity Missus....

Not corrensponds to my tests at all. Especially bad delta behaves on different textures data. As SREP is just a simple LZ77 with extra-large dictionary, it can't say if the data consists of binary tables or not.

In my brute-forcing sctipts is always one of the steps, but as i said above, it rarely gives any benefit, but makes compression worst in much more cases.

Mad Max is a good example. It hase astonoshing srep removal rate, but using delta will hurt the compression ratio due to lots of textures inside.

Corepacks Just use a modified Version of Precomp. They Use Precomp+Srep64+Lzma64.

Modified precomp? :v since when they know how to program?

Razor I'd like to ask you because i saw a Zlib1.dll which is around 50 kb , the one we use is around 100 KB I found it in SYter Repacks so any difference ??
Updated
the same as FitGirl the both are using Zlib1.dll with precomp038 which is 59 KB Those 2 Guys are using same methods / tools almost the same
updated
Same as precomp 321KB , original ~600kb less size than usual so is they using a modified version or they are basically compressing it ??
updated
also precomop043
original size 1.015 KB the one they are using is 1.160 KB now i don't think they compressed the files I'm not sure about it's modified or not But maybe i'll do some speed tests

Sorry my fault.
They uses 1.160 KB version of Precomp which contains cls patch but with brute.
