Dragonis40: Try it use very slooow settings:

xZLib(old Xtool 0.12)+srep:m3f:a0(srep 3.92!)+lolz:dt:dtb1:dtw1:dtm1:dto1:dtd1:d512m:fba4096:mc1023:tt16:mt1:ldmf1:ldc0:ldl5

Questions: The *.bsa archives contain goodly compressibble raw/wav audio files? MP3's or any? Videos?

Alternative1: xZLib+srep+delta+lolz
Alternative2: xZLib+msc+srep+delta(used or not)+lolz

Thanks for your reply! How can I find out what *.bsa files contain? Do I have to use any tool?

@kj911
Don't use LDMF if you are using srep, no point.

I've made some test:

xt_zlib+srep_old:392+lolz:dtb1:d512m:mtb96:ldl5:mc 1023
21 files: 8,588,002,315 byte => 4,776,969,655 bytes. Ratio 55.62% (17127.25 sec)

xt_zlib+srep_old:392+lolz:dt:dtb1:dtw1:dtm1:dto1:d td1:d512m:fba4096:mc1023:tt16:mt1:ldmf1:ldc0:ldl5
21 files: 8,588,002,315 => 4,764,178,217 bytes. Ratio 55.47% (35516.07 sec)

The last combination is NOT worth it!

Several .bsa files are plenty of .ogg file (hundreds), so I should extract these .ogg files, compress and before the end of installation make a backup of original .bsa file. I think it takes very long to install the videogame!!!
