[SOLVED] Harry Potter and the Half-Blood Prince DS - "Neko" files

[AlphaTwentyThree]

Hi there!

Luigi has updated his fxp script for the DS version (thanks for that ) but now there's another problem: The extracted files need some other transformation.
Here's a picture of the "Neko" archive that contains the SDAT:



What has to be done to correctly get the data here?
I've attached said file for you to take a look.

The main compression used on Nintendo is lz77wii but here I don't see any compression of that type, I don't even know where the compressed data is supposed to start... 0x20 maybe?
Not even lzss returns good data.

Well, I cut the first few bytes of the files up to the "Neko" identifier. Here's the full file:



Does that offer more insight?

[AlphaTwentyThree]

Yeah ok, it's lz77wii, just like you said. Maybe you could also implement it into the main script? Would be cool.

[aluigi]

But the script I updated few days ago (0.1.2) already implements the lz77wii compression, doesn't it work?

[AlphaTwentyThree]

Oh, my bad actually. I added my function identifier to the script and it had an error inside. Sorry about that.
Works of course.
