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

[kj911]

Analyze few compression methods the SC2 game. The Hungarian 1.31 version (with extra Multiplayer maps, size ~80MB's.) not compressible smaller than 890-900MB's sizes without lossy BIK reencoding. The game installed size its bigger than any localized releases.

Size differences, between Hungarian (Retail) and English (Steam/Uplay?) versions:

Full sizes: English: 1568MB, Hungarian: 2249MB

Video files: English: 321MB, Hungarian: 433MB
Sound files: English: 661MB, Hungarian: 760MB

Some game files recompressed use SREP+LOLZ (and any variants) compression methods, saving few thousand MB's. (Dat1-3+text.sfxdat, Orig: 250MB --> 235MB) Snd1/2 archive. Orig: 72.9MB --> 67.8MB. Biggest savings available from only the BIK videos. Orig: 375MB --> 309MB's size. Full savings, around ~90MB's. Original compressed packs size: 976MB (with SFX-modules. Total 6MB's extra size in 10 files. Raw Arc only size: 970MB)

Dramatically reduce the video files to smaller than 150-200MB's size required to fit the game into one CD. Files list its added from analyze the game.

UPDATE: Found old my recompressed BIK video packages these game. Any files repacked with LOLZ and any ones. I will finding enough 15-20MB extra data reduction to fit the game to one CD!

Videos: 141925kB (with BPK+LZMA compression. Unpacked size: 195920kB)
Binaries: 10911kB (without SFX module, the old archive)
Snd4: 162663kB (LZMA only)
Snd3: 105523kB (TTA+REP, its best results. MSC or LOLZ not better)
Snd1-2: 69498kB (SREP+LOLZ)
Data1_2_3_text (one archive): 240006kB (xZLIB+SREP+LOLZ, Unpacked size: 1040382kB)

Any extra files required 3241kB's space without installer. (Old installer size: 626kB) XT+LOLZ+CLS extra files required ~3MB's space in compressed format.
