Senran Kagura Estival Versus (Vita) (.tpk)

Post by Methanol »

The .tpk is just a container, with no encryption. I can pick out sections that make up a .gtx and convert them using GXT convert. I'm just not sure how the structure is, and hopefully someone can offer some help.

Download of Chunk03.tpk and Chunk03.bin

I guess that the extracted files of this Chunk* are some sort of custom models or something similar ("tmd0")

Perhaps the Fnames directory files might be helpful?

This needs the decryption key. A link with the key would be nice.

Sorry about that. Here's the decryption key:

Code: Select all

Yes, this definitely seems helpful. I wonder how the filenames relate to the chunks.

In other news, I wanted to say the current output can be more granular. I'm posting a sample 000004ff.vap from chunk00.tpk and the 3 files that it contains.

The space (headers?) between each actual file differ, between 192 and 336 bytes.
The names may take up more than 64 bytes, which I can post an example of soon.

I've also marked some features of the file on the .hbk, for use with Hex Workshop.

@Methanol
Thanks for the hbk marks.
Now we can see every GXT textures using GXTConvert.
