i think compressed file that enough clear.

eg, "AddressX.............AddressY" compressed "AddressX.../Q.Y" because Address had been appeared.

biger than 256K cant upload.

Well with limited time I guess I better at least say something. The Compression is LZO. I can get it to decompress but I have not found the exact type it is to reproduce the same (decompressed back to compressed) data.

I've also glanced briefly at some Unreal stuff, they claim association with LZO but does anyone know of the exact type? I have about 30 or more types to go :p

The images looked to be TGA/BMP. I don't think I saw a single DDS hehe.

I haven't touched it. I have a an overwhelming schedule and I have no plans to touch it.

The file format is a Big Endian version, with some differences I assume,of the .U format I believe. I haven't looked in quite some time. The initial 4 bytes give it away just google a bit.

The files are LZO compressed no doubt about it. I've decompressed them and poked the files. The goal was to replicate 100% decompress/compress the package to match it byte for byte. I did not do this as I didn't find the correct LZO scheme used.

I was using initially for the test a LZO decompressor Hunter made some time ago for some Fable tests. I've reworked a new one for various tests. You need to pay attention to the data at the end! Look you will usually see 11 xx xx xx etc at the end, this is dependent on the trailing data allowed.

Hi silver! I'd love to talk to you about an old post you made on farcry evolution here:
viewtopic.php?t=1827

please reply to the PM i sent you, I realize this is off topic....

Just to show you I'm not full of crap from the file you posted the Compressed portion and the decompressed portion of the same file.

The Compressed file is obviously more than one chunk of compressed data. That is why the decompressed one is smaller than the compressed. This was just a quick test to show decompression is correct format.
