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

FreeArc 0.67 (March 15 2014) creating archive: Conversion_Output\Data1a-01.bin

Compressed 3 files, 1,580,482,272 => 1,292,223,837 bytes. Ratio 81.76%

Compression time: cpu 1.08 sec/real 154.58 sec = 1%. Speed 10.22 mB/s

All OK

As for the WEM files. I tested a bit with the language files and you will gain just a small amount of ratio even if you group+squash the files into one single file.

g00s001 WEM files 733MB -> 672MB

Just make sure to exclude WEM files which are less than 100kb in size if you process them. There is always a magic line for the WEM files for which - if they less than size X - processing them will yield in zero ratio or sometimes even in negative ratio.

I feel very silly now! It just so happens out of the 3 videos I sampled all had the KB2j signature, talk about rough luck. I need to start packing WEM files, never had massive luck with them due to the annoying packing process, appreciate the advice!

Don't hassle with the language files. Imo they aren't worth to process with wemtool (just ~15mb per language if you skip all files below 100kb).

You can extract the WEM files with this tool I guess (I use another tool without 2GB limitation)

A bit messy but if you get any errors with that 2GB file limitation, just search for the first riff wavefmt stream somewhere in mid-file offset, then split this file into two halfs and use the extractor if you don't have other tools by hand. Like I said this is a bit messy but should work as a workaround. After split and extracting WEM files, erase WEM files with xtool erase command. Afterwards just merge the two files back into one file, then decode back WEM files afterwards with xtool. The rest is up to you.

If I remember correctly the total save with processed WEM files is about 200-250MB in total without language files (input ~1.27 GB).

Old TRS2004-2012 recompression issues

2 Attachment(s)

Any tools/idea from precompressing old TRS game series? Aka TRS2004 to 2012 games used *.ja archives. Newer TRS2012 SP1 and newer 20xx versions use (probably uncompressed) only *.tzarc game files.

Very old TRS2004 related *.ja extractor added and *.ja archive sample from the TRS2012 game.

In last stage, the overall best methods from *.ja files:

RAZOR only (stdio version) with 1023mb dictionary size, the files shrunked to 4.22GB.

Any rest files use in: xZLib/xtool+msc+delta+srep+lolz or xZLib/xtool+RAZOR

Output size differences abysmal, less than ~0.5MB's compressed size. (RZ used 256MB dict size. Larger probably get in 0.5-2MB extra size reduction.) The game not easily fit to onto ONE DVD5 sizes.

Maybe use key from Bodycam-Win64-Shipping.exe to find out.

Hi everyone, may I ask. Maybe someone knows the right compression method for the Ace Attorney Investigations Collection game? This game uses the unity engine and this is a sample file:

Hi Danziel

Suicide Squad Kill the Justice League uses. zlib+srep+lolz
this game will not get compressed alot i believe that you will save about 20% compression..
