Sekiro Shadows Die Twice:
Break Game into 3 Section:
Section 1:
Videos: BPK
openingmovie.bk2 copy this file one more time and rename it to "openingmovie_hi.bk2"
stafflistmovie.bk2 use my BINK encoder to encode the first 6~7 Megabytes
This will result into popping the First 2 3 seconds in the end with Sekiro Display

End file = 221.mb
Section 2:
Audio and Executables use this:
7Zip_Shelwien Bat
You end up with 564MB file.
Section 3:
Game files:
arc\Arc a -ma9 -ds -lc4096 -ld4096 -di -i1 -ep1 -ed -r -w.\ Setup-3.xarc ^
-mpoodle+srep:m3f:a2:l256+lolzi:d128m:mt2:ldmf1:ldc 0:mc1023:mtb64:x0 "D:\Games\Sekiro Shadows Die Twice\3\*"
End File=7.95GB
Total: 8.72 GB
You can do a bit more if you absolutely MUST
Use Bink2 encoder, to lower 720p the videos,
Use higher and single thread lolz to squeeze a few more MB
Enjoy
