@Amsal : i see what you want to do u wanna unpack all the files with quickbms compress srep+lzma for better compression.then install game then rebuild the unpacked files to match correct md5 like the original pack files so game can work.basically you wanna do a fitgirl repack.which is crazy cause the install times is just madness and the work behind it is crazy.i feel sorry for your hard drives during repacking and install.

as you said you can unpack with quickbmas just you need to know how those pack files are repacked you can check the headers to see and repack the same to match md5.there are tools on the quickbms site like (offzip as a example) to scan headers to find out so repack file with the correct encryption and md5.its alot of work as i mentioned.
