OK!
Read this:
This is the compression I used:
GTAV_1 (Disc1)=srep+lzma
GTAV_2 to GTAV_14= no compression (Disc2 to Disc14)
To change compression of "GTAV_14" do this!!
1-Right click on "compress.bat" and choose modify.
2-Scroll down to Data14 section and change:
from
arc a -ep1 -r -w.\
[email protected] -dp"%choice1%" .\GTAV_14\%arc%
to
arc a -ep1 -r -w.\
-msrep+lzma:a1:mfbt4:d256m:fb128:mc1000:lc8 [email protected] -dp"%choice1%" .\GTAV_14\%arc%
Please test and report back!!!!
