Tool/script to unpack/repack unknown format [Mortal Kombat Shaolin Monks ewdf]

[Alpha1001]

Hi, I would like to know if someone can write for me a tool or a bms script to decompress/recompress this archive? https://drive.google.com/file/d/1sHDLKH ... p=drivesdk

[aluigi]

Name of the game?
Remember to write ever the name of the game in the title.

Hey aluigi, the script works fine to decompress the EWDF, but the recompression/reimport won't work "the file is too big" after decompressed. I've searched on the Wikipedia about the Deflate algorithm, the ZIP format uses it, I've tested with the Winrar and the PKZIP but the game crashes. I think that because of header in the ZIP archives are differents, the filesize is in other offset... So, you can make/implement an small tool to recompress this Deflate version specifically to the game?

I have updated the script for automatically acting as rebuilder if the input file doesn't have the ewdf extension.

Usually I never write rebuilders but this format was very simple

Hi, the script works to rebuild the ewdf decompressed, but if I translate all the texts of a file that I have here, keeping the original filesize (4390 bytes) after rebuild the ewdf becomes larger and the game freezes, now if I translate an small text block the game works fine. There is something with the repeated strings or chars (amount details) even keeping the original filesize? Is possible to achieve always the same size of original archive keeping the same size in the modified file (improve the compression level)?

I have just noticed 2 additional fields at the end of the ewdf archive.
Script 0.1.2

I've tested here, but this message error is showed after select the ewdf decompressed http://imgur.com/ZvkAhuN

Here everything works perfectly:
quickbms.exe mksm_ewdf.bms y_hud_v01.P2N

Now is working here too, thanks!

I've inserted several files and so far it has worked fine, but now I've found that file https://drive.google.com/file/d/11z_Rtw ... p=drivesdk that is making the game freeze after recompression. Maybe there is a difference in compressing this file to others or does the script have to be adapted to it? You can check this file, the decompression works normal, but after. recompress the game freezes

[aluigi]

Give it an ewdf extension because the script is instructed to extract the files with such extension and repacking those with any other extension (or no extension at all like your sample).

[Alpha1001]

After I decompress this file the extension is .bin (a text file called h.bin). The problem is with the recompression, I don't know if the game uses CRC checking for this file to detect changes in the original content, because the others ewdf works fine recompressed.

I tried using the script to unpack GAMEDATA.WAD from the E3 build of the game and it's not working. Not really sure what is different about the older build's .wad file but here it is if anyone wants to mess with it:

1.2Gb? Remember to use the filecutter script with big files, it makes analysis a lot faster:

Need some Further help with this script I am using version 1.0.4

The bms unpacks GAMEDATA.WAD, in those files there are additional .WAD files (example: ES_00000047.WAD)
I tried running the script again on these but get the Error (see attached image)

Tried changing the extension to .ewdf also didn't work.

Download file for further analysis:

@TotalMK
I updated the script to skip that additional byte.
Let me know if it works better.

I gave it a go on the wad I posted and another .wad but unfortunately it didn't work
