You almost there. All that you need is to insert missing "python": At least it must provide readable error.

Just save script as .py file and run in commandline or powershell like this: Or You can also pass an output directory like this: Hope this helps!

Here is a little Python 3.6+ script that do the work you wanted. Please note that you need an Python interpreter and Pillow library installed (pip install pillow). Hope that helps! from PIL import Image from json import load as json_load from pathlib import Path from sys import argv, exit def split_...

I've already gotten the huge collection of .dat (and other) files, now what? There is not a big amount of GUI tools, so I can recommend DEMD DB program (latest build: https://yadi.sk/d/qUxdTmJa3MxHEs). It allows to preview and convert textures, most of models formats, FSB (audio) files. If you used...

Files are encrypted with XXTEA algorithm which is commonly used in cocos2d games. First two bytes is XT signature, which must be skipped before decryption. Example of image decoding (Python3 + xxtea library): import xxtea if __name__ == "__main__": with open("chr755a01.png", &quo...

Well, old script or LN_decode still works for files that use old key. For the files encrypted with new keys you must change script AND aquire 26*26-1 = 675 new keys. After that you must use right key that chosed by version_a/b fields. Sorry, but I can't say more as it will against forum rules (rule ...

Hi!
It's an old problem in my program. It's a false positive message, i.e. in reality unpacking completed.
You must just open created NameMap.txt (Open unpacked DB).

I hope someone can help me method to decode this ktx file. Attachments include the ktx file and the original png file. Well, this is the encrypted textures. You can see characters "dr***png" at the end of files. They have known file structure, but sharing the decryption keys is prohibited.

No, this looks like raw RGBA pixels of 16x16 tiles with different start offset.
Maybe this is level map file or just packet tileset.

From which game version did you take sample .ktx file?
"png" signature also was in .ktx files, it's just flag for chosing right encryption method.

So you have an disc image of PSX version in .bin+.cue file format, right?
First of all, you can convert it to .iso and mount using windows explorer.
After that you can find archives and use existing tools on them.

@aspadm, can you link to some documentation or at least some discussion regarding this format? Ow, looks like they changed format. Previous was like this: byte data[len-8]; // len = file size, must be a multiple of 8 char sign[2]; // "dr" unsigned char version_a; unsigned char version_b; ...

This is custom made file format with blowfish encryption that was reverse engineered several times.
Latest version was deleted as tencent started the pursuit of enthusiasts.

Oh, well, your friend just posted this on several forums. In any case, looks like game has two formats: for tiles and objects, which are the parts of game level. Provided example file is object file. Object file structure (in the Kaitai Struct .ksy format): meta: id: obj file-extension: obj endian: ...

This is custom format. I think that there must be a lot of variations inside. In your example file 4 images that looks like a cover of the "Rock N' Roll Racing" cartridge/disc. If you are familiar with Kaitai Struct and python, you can extract it using this format description: meta: id: im...
