Inside the game http://int0thegame.blogspot.com/
There is a tool. It's called mapledump. But it's on Korean (or Japanese or something like that). It's written in Delphi and it's closed source.
I think that this tool is just a "translation" of the Python Script as the output looks the same.

I wanted to write a Object Pascal Tool, too (With FPC and Lazarus). But I'm still having trouble to read the Python script... I know the general process of what the script does, but my Python knowledge is to small to fully understand it...
And another reason, why I am not coming further: It's hard to find all the needed functions and types for Object Pascal - zlib, all the datatypes, the basic file reading - just everything is different...

Anyone else made a script or a tool in another language and likes to share his knowledge?

If the script was at least in C, but Python? Why it had to be in Python?
Yes, it extracts all Images, fine. But it would be better to have a tool to browse the wz-files.
The point was to figure out the file structure, and python is a very good language to quickly put together a prototype. If you believe it's better to have a tool to browse the files, why don't you make one and release it?

Python is a very easy language to learn, and lambda didn't use anything too exotic to write the script (apart from zlib, but that's a standard dll). If you have any questions, there are plenty of places to ask (here included).

"If you want one why don't you make one?" - That's a really dumb argument. It's the same like "So, you want a Mercedes S Class? Why don't you built it yourself or why don't you earn all the money and buy it?"
You don't need to be able to make anything better to see that something is not perfect. If I could do it better I wouldn't ask but do it.

Yes, the goal was to find out the file structure. But I can't see it here. All I see is a Python script. People who don't know Python can't write a tool in another language. I could write a tool in Object Pascal (maybe also in C# .NET, what I am currently learning) - if I just could read the full Python script to find out the file structure.
It's not so much about the algorithms (loops, calculations, boolean operations etc.), they are almost the same in any language. But the problems for many people are the "Pythonish" stuff (e.g. the struct.pack and .unpack stuff, the string handling, file access is easier than in other languages, in my oppinion Python code is hard to read etc.)
So it's not possible to just "translate" the script.

That's why I asked if someone already made up a general, language independent overview about the file structure. That's all I need to write a tool.

I'll answer your questions in order:
"Anyone else made a script or a tool in another language and likes to share his knowledge?" done, but i'm not sharing code, though I can tell how it works
"If the script was at least in C, but Python? Why it had to be in Python? " that's what I answered above.
If you want the answer that goes with your mercedes allegory, you can pay someone to make it for you.
Now, if you have specific questions, I'm willing to help.
@AngelSL: I'm kinda short on time in general, so can't really look at the code, but is there an error message (are you running it from the command prompt?)? Are you running the program directly on sound.wz?

Anyway, if I put mp3count = 0 in the start of the dumpMp3 block, then it just extracts ONE mp3.

try this:

Code: Select all

def dumpMp3(f, size, endOfBlock):
  startOfMP3 = endOfBlock - size
  remaining = startOfMP3 - f.tell()
  unknown = f.read(remaining)
  g = open("%d.mp3" % remaining, "wb")
  g.write(f.read(size))
  g.close()
  f.seek(endOfBlock)

filenames will be pretty ugly, and it may not work on older computers, but it should work....

That only extracted 3 sounds, 1 throwing star, 1 arrow shot, and one other silent sound. The rest were just htmls..

I hate to bump this, but Sound.wz is the only barrier that blocks me from releasing 00042 extract of MapleSEA

Are there more error messages?

AngelSL · Post by **AngelSL** » Tue May 29, 2007 1:21 am

No. No errors. But they only extract 3
Still, the floor tiles aren't in Map.wz... Anyone know where it is?

Which floor tiles? They seem to be in sub folders of Map.wz/Tile/

And if there are no more errors, the problem is probably deeper than what I can solve right now.

Theres no Tile folder!
EDIT: Found out why. Theres an error right after it tries to extract the Tiles.
Its something like:
Unknown: 115 Expecting: 15 or something.

That means that there is a bug somewhere in the decoding....it might be that it's expecting a 0x1B block, but getting something else, or vice versa...

Maybe someone else can provide a solution? (too deep an error for me to solve)

Omega why cant you share you files you have exetraded?

Easy answer, because I choose to. Long answer, it contains the code to decode the new kmst encryption, and I don't have the time to rip it out. Soon after we figured the regular version out, they changed to this new encryption. I'd rather not have to figure out a new encryption scheme.

so can you jast upload the files you extraded?
to a srver?
put it all in rar put it in srver to the night and in the morning share the link?

and can you tell me your msn?
