UltraARC for Inno Setup (Conversion Tool)

[psygonex3]

Not sure why but it works under win8 but not win7 i did remove alot of language packs from win7 but i also omitted the ones not needed in the setup.

I think I'm doing something wrong here.

I've used UltraARC now a few times for my compression needs, but I can never seen to get decent compression from anything, I can only really get 300mb or so compression over the original folder size.

Here's the UltraARC log:

Pastebin

I am compressing LEGO Indiana Jones here (which is mainly large .DAT files, with a plethora of small .OGG files since the audio is external to the .DAT files)

Can anyone see what I'm doing wrong? I am using XTool (zlib) + SREP + LOLZ + ZSTD. I don't know how necessary precomp is as well as I'm not too sure if ZSTD is needed on top of LOLZ.

If anyone cna find out how to gain much better compression, I'm all ears

Use oggre for this

No, not really.

I don't know about this game, it could be that the game files are crypted. Maybe try quickbms and extract the files if possible.

Thanks KaktoR. While we're here, I am fine using UltraARC the way I am, right? If I try a different game, everything should run as normal (normal being I can reduce file size by GB than MB)?

yes, but LOLZ and ZSTD are the final compressions, so choose one of them, I refer to LOLZ with this method:
lolz:dtb1:dto1:dtm1:dtw1:dtd1:d256m:mtt1:mt4:mc102 3:gm20:fba4096

my common method usually:
XTool+srep+delta+LOLZ

if there are many files like .raw, .dds, .mp3 or anything try:
msc+XTool+srep+delta+LOLZ
or if just .ogg with another files try:
oggre+XTool+srep+delta+LOLZ

So this is just XTool + SREP + LOLZ. How necessary is precomp (in any situation)?

Precom means precompressor and it's simpler to xtool or ztool (cause they are precompressors too).. But xtool is effective (with zlib/zstd/lzo/lz4...)
AFR is an example of precompressor (but it supports only .forge files I mean files which were made using Avilnext engine of Ubisoft)

Precompressor is sometimes necessary sometimes it's not and it's hard to tell for me.Like I did packed some files with xtool_pzlib+srep+lolz and got 58% ratio
But when I used srep+lolz only I got about 60%.. in this case precompressor didn't worth my time that much

[devil777]

Yes dude... If it has files to reduce on...

Like forge file can be done well via AFR+srep+loz. I mean you'll get good ration over the the file.But man it hurts when it comes to decompression.. The AFR is slow

[devil777]

And entai44.. for lolz which parameter u would recommend??

I generally use lolz:tt1:d200:mtt1:mt3:mc4 (it's fast but not ratio wise,atleast it gets me 2300k/sec)

I'm on HDd don't have any Ssd.. which one u would suggest for speed in com+Ratio wise?
