3.92 x64 and 3.2 x64

Greetings 78372, so finally thanks to your cooperation I was able to find the culprit! I tried exact same settings as you and it worked. The difference when it started crashing again was when instead of "static" chunk size I selected "take from ini". Even though your generator.exe created cls.ini with chunk info, and I did copy it into main $FA/bin folder, it would still crash. Only "static" worked.

I dont know why "take from ini" dont want to work here, but it explain why other cls's also wont, it have to be set to "static" during dll generation. If you have any idea why this may be you can let me know. I am glad I can get it to to work at least this way, your tool is finally extremely useful to me.

Also to let you know your last lolz cls work fine for both packing and unpacking. I noticed no metadata string when looking into dll through rez hacker, I guess you made that cls different way and not through generator. Is it because 2 different exe's are needed? Since I was asking already if there is a way to generate cls with your generator that can use 2 different exe files for packing and unpacking, like you did this lolz cls. I would love to make one's for many other compressors.

Anyway, thank you it was very helpful.

The cls I uploaded was fully programmed in general, no generator or such things because it uses no chunks(so no loss of ratio) and uses original cls-lolz.dll

The files there are these:
lolz.exe = lolz_x64.exe
lolz.dll = cls-lolz.dll by profrager
lolz_x64.exe and lolz_x86.exe = cls-lolz_x64.exe and cls-lolz_x86.exe


I had to rename those to keep compatibility and remove bugs.

In compression, only lolz.exe is needed.
On decompression, everything is needed except lolz.exe

If profrager updates lolz, you can just rename the files and use them with this cls, no bugs are expected in that way.


The generator needs to be updated, I am not having time(unfortunately) but anyways I will try to remove the bug you reported(thanks for it) soon so that you and others could use it

Hi Friends,
someone can help me? I used this CLS (thx 78372) for compression and decompression via Prompt/Command (Arc a and Arc x) and it works great.

My problem is when I have to use it in my innosetup script.

I added this lines:

The setup is compiled correctly but when I start the installation "unarc.dll return error -1"

For information I have not included anything in my arc.ini since the CLS decompresses perfectly the same file ".bin" via Command.

Where am I wrong?

Thanks in advance & Best Regards

compressed mass effect from 10.5 to 3.03 gb using uelr srep and lolz.

Various errors can be there, doesn't seem to be a cls error. Try with original cls unpacking from profrager, if the error persists, then it's not my cls error.

Compressed Batman arkham Orgins from 17.4gb to 7.79gb using srep nz uelr and lolz lzma

you should also consider the de-compression because without the ability of getting your data back it's just a waste of time

Sorry i didnt understand what u said.
if u r saying that it will not decompress. It decompress successfully and all the files were md5 perfect.

then you have done good and your data is safe

uelr is indeed a great tool.
bpk is only good if you want to save some mb, it doesn't make any sense < 500mb i think. But if your game has f.e. 3+ GB of bink videos, it's great.

lolz is too slow for me (reminds me of old precomp days, where compression take over 8 hours lol).

oggre not tested yet, have not that much sample data for testing.

use 4x4:b64mb:lolz:mt1 xD

You gain the speed in decompression, lolz is faster than rz in decompression and can reach 250mb/s if your hdd can load it.

If you have a lot of RAM and at least 8 thread in CPU, you can use "mt8"

The best thing what i like about lolz is it runs silently in background with disturbing u. u can do ur normal work with ur pc
