to decompress lolz archive you can use cls_lolz_x64.exe directly without cls dll. if youre trying to unpack fitgirl archives this is how you do it.
Code:
[External compressor:magic2]
header = 0
unpackcmd = "cls-magic2_x64" d $$arcpackedfile$$.tmp $$arcdatafile$$.tmp
same goes for unpacking any other version of lolz without cls dll. this uses stdin/out. if you want to unpack from file you have to something like this.
Code:
cls_lolz_x64.exe d < "compressed_data.lolz" > "unpacked_output"
