One final question,

I'm trying to program a re compresser/de comperessor

The C String at MEMORY_FILE10 binary is the Decompression Table right?

No, MEMORY_FILE10 is just the compiled x86 function, the executable code.

Ah thank you, so much to learn!

Hey,

is it impossible to reimport with this script due to it being chunked?

aluigi, posted Mon Oct 24, 2016 7:23 pm (18316)

It's not possible to reimport the files because there is no recompression algorithm available.

Quick question, aLuigi: would you share the source code used to compile that MEMORY_FILE10 DLL?
Did you have to implement the whole of what lsaint described in his long post?

There is no source code.
That one is the original code taken from that tool you linked.

Hi,

I'm looking into this game also, and apparently there are RIFF files in one of the archives
and the current script stops when it see's them. I've uploaded an example

Can you do an update?

also, what exact kind of compression is it? I've read the thread and the OP's post is hard to follow.
It appears to be some kind of variant of Lz77?

ahh finally!

So here is the binary Luigi dumped, translated into a working program in C.

right now it can only handle single files.

now on to the long road to figuring out re-compression.

decompress.c

Well done, less work for me when I will add it natively in quickbms

Glad I could be of some assistance!

do you have any tips about understanding re compression?

I suggest you to post on http://encode.ru, they can write a compressor on the fly.

Hey,

Thanks for the help luigi and the guys at encode.ru! I have now achieved semi working compression....it's larger than the original but can be decompressed by the girenaxv program. It appears there is another compression on top of the lz and the rle: it avoids using markers for repeated literals. I haven't figured it out yet.

but if anyone is interested I'm attaching my test program....

slow and steady
