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

[Masquerade]

I'm taking a look at Terminator Resistance, and however I'm encountering an error.

It's an Unreal Engine game, so i'm using xtool(zlib)+srep+lolz, however I always recieve the Failed CRC check error during unpacking. This always seems to happen when I use XTool, because I can use srep+lolz on their own without issues.

Here's my Arc.ini:

[External compressor:xzlib]
header = 0
packcmd = xtool e:precomp:t100p:zlib - - <stdin> <stdout>

[External compressor:srep]
header = 0
packcmd = srep -m3f -l512 -v2 $$arcdatafile$$.tmp $$arcpackedfile$$.tmp

[External compressor:lolz]
header = 0
packcmd = lolz_x64 -dt -dtb1 -dtw1 -dtm1 -dto1 -dtd1 -mtt1 -mt4 -d64m -fba4096 {options} $$arcdatafile$$.tmp $$arcpackedfile$$.tmp

I'm not sure what could be happening, because other games such as No Mans Sky where xzlib is also useful has the same unpacking error.

I am using XTool 0.12, lolz v22c4b and SREP 3.93 Beta.
