Overlord Xbox360 decompress

Hi Aluigi,

Can you help me?
I want to translate this game, but i can't uncompress some files.
These files look like they're compressed with xcompress (LZXNATIVE), but their headers are a little different.
I can't uncompress them with xcompress_file.bms

Here are some samples:

Thank you in advance

There is just an uncompressed size 32bit at the beginning but everything looks ok, except that decompression fails.
No idea why since the fields are correct (checked with xcompress_file.bms).
This is the script that was supposed to do the job:

Code: Select all

comtype xmemdecompress
get SIZE long
savepos OFFSET
get ZSIZE asize
math ZSIZE - OFFSET
get NAME basename
clog NAME OFFSET ZSIZE SIZE

Thank you Aluigi,

Are you sure, that this file is valid native format?
I don't think so

Valid native format:
Magic: 0F F5 12 EE and after: 01 03

This file:
Magic: 0F F5 12 EE and after: 01 00

and i think the header of this file is 4 bytes longer.

Do you have any other ideas?

Thank you

Hi Aluigi,

If I use your script with the comtype lzfu, it seems like it's trying to unpack something meaningful.
But it's not exactly good, because it looks like there's a lack of data or it use a different kind of compression.

Can you check for me? Can you look at it for me?

Thank you

lzfu is for text only, it's a common false positive in test results.
