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

[ZakirAhmad]

Used precomp042+srep+lolz on main game .pcc files.
srep+lolz on audio files
srep+lzma on .sfar dlc files
bpk +srep on bibk video files
and srep+exe2+delta+lolz on remaining files

Someone here compressed ME3 from 24.3Gb to 8gb.He doesnt mention how the hell he extracted .sfar dlc files.
After extraction r files md5 perfect.
Here, we share methods not conceil it, this thread is ment to provide info, how to achieve this size. I tried to contact hime but he didnt responded.
I tried to use dlc extractor and xdelta to make it work but after comparing (recreated .sfar )files with orginal, xdelta produces orginal size patch which is useless. if anyone know how to do this let me know.
My theory about how (i guess is his doofoo) compressed it from 24.3gb to 8gb is he extracted .Sfar files and then recreated .sFar from extracted content without useing lzma compression (hence the game size 24.3gb).
Cp has also compressed mE3 from 16.5gb to 11.5gb (compression ratio of around 70%) which is same as mine that means they have encoded videos.
My orginal game size was 24gb after removing French, Italian and German languages, it came down to 19.2 (with single int(english) language).

Someone here suggested using lzma precompressor by shelwain, it has a issue, it doesnt allow using external compressors like srep lolz on precompressed file. what it does is, it first precompresse lzma files, then uses lzma compression with high setting on precompressed files.
BTW it supports stdin stdout(someone might want to try).

.SFAR files used in Mass Effect 3 uses LZMA compression. Normally it is a very very stupid idea to do precompression of LZMA because you know its going to be very slow unless you have a proper way of doing it in MT. To match the data/size with originals so that you dont get large xdelta patches, you have to match the LZMA parameters,block size etc... as it was used in the originals.

And for Shelwien's tool, you are confusing plzma. He has also created a lzma recompressor with no internal compression so that you can apply further compression but its very very slow and for advanced users.

i don't remember which sfar extractor i used it probably the one with the mod, use f*cking google and BTW STOP SPAMMING my inbox

Nevermind, I spent too much time on this repack. I am fed up with it.
