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

[Dragonis40]

Hello everyone! I've tried to compress Cyberpunk 2077 v1.52 HotFix 2 using the following mask in UltraArc v2.9.0.0 R9:

MASK = srep+GLolz/$mscpack=msc+srep+GLolz/$anvilpack=xtool+srep+GLolz/$deflate=precomp+srep+GLolz

-) $anvilpack is for .archive files (i've used XTool_2020 v0.5.3 with Cyberpunk plugin);
-) $deflate=precomp+srep+GLolz is for .pdf, .png and .bin files (precomp version is 0.4.8).The command for precomp I've used is the following:

packcmd = "PRE\PRECOMP\precomp.exe" -d10 -cn -brute -o$$arcpackedfile$$.tmp $$arcdatafile$$.tmp

During decompression, when setup.exe tries to decompress "CP2020_Sourcebook_EN.pdf" file, an "Unarc.dll returned an error code: -1" error appears. If I try to decompress setup.bin file using a simple .bat file, there's no issue.
I don't think that .pdf file is corrupted (it's the second time I've tried to compress the videogame with a CLEAR installation, but the issue is the same). Where am I wrong? Thank for your answers!
