Help, please, unpack graphic files from the browser game "Mesolithic".

Wolf walk animation

there is zlib compressed data in there, extracted there is 708x708 jpg image
sprite sheet with another zlib compressed section and table at the end of the file.
this bms script will extract the data as is: the other zlib compressed section when decompressed contains the 708x708 8bit alpha mask for the jpg image.

and this bms script will get you just the jpeg image

This code does not work for me: Only the second code works.


Sorry, is it possible to unpack in .png format with a transparent background?
For example, like this:


P.S. Sorry for my English, I use a translator.

sorry, fixed!

like i already mentioned there is recursive compression in the file,
after you decompress the sau there is another compressed section in the
decompressed sau, this compressed section is the 8bit alpha mask you seek.
when you extract that it has no header, and it has to be combined with color
image by hand unless someone gets crafty with a new script.

Acewell, help, please, disassemble.

Acewell, sorry for bothering you. The ".sau" file must contain another file (in text form), which is responsible for the coordinates of the sprites. This file can be found and unpacked?
Without these coordinates it will be very difficult to cut the sprite sheet.

the first bms script unpacks the whole sau file, there is no text file only a binary table at the end.

i don't know, looks compressed to me.

The first bms script unpacks everything in ".dat" format.

yes, it was a single compressed container.

.... in ".dat" format.

dat is just a meaningless extension, or would you rather windows see it as "file".

i have nothing more to add here, maybe someone else can do better.

Thank. I just clarified, because the first time I did not understand you much.


Acewell, I'm sorry, I have another request for you. Please try to unpack this file (.atf) from the Forge of Empires game.

i need more samples to make a script.

Acewell, sorry again. Can I unzip the ".bin" file?

what bin file are you asking about?

i don't see anything in it.
