Ok, I just thought, lets try if it will extract fine or not, so i taken a file from The Sims 4 game - ClientFullBuild0.package
And i got that it extracted the files but I got CRC Check Failed in the end, but the files extracted successfully, but as it is multithread, so I have only dual core processor, so it uses only 1 thread from my pc and as razor said 64mb at a time, so it decompress 64mb and then extract it and then again extract 64mb and so on..
and here, how i made it works -
I tried this with masked unpacking section v2.5.
1. Copy brute.exe from fast brute folder and paste/replace it in unpacking section folder
2. go to arc.ini of unpacking section and paste/replace this -
[External compressor:brute]
header = 0
packcmd = brute <stdin> <stdout>
unpackcmd = brute <stdin> <stdout>
Now, i am going to see if really crc or md5 is different or not with different checking tools
EDIT:
I checked both files with QuickSFV, and CRC is Mismatched, I hope Razor will fix this issue!
