Natsuiro High School: Seishun Hakusho (.cat & .gtf)

[ssringo]

Random T Bush created a script that (apparently) works with the models from this game but there isn't a working script to extract the archives (apparently someone sent him extracted files but hasn't shared the script as far as I can tell). I've tried scripts that work for other games from the company that use this format but none work. The thread with his import script can be found here. He has stated he'll get around to looking at extraction at some point but he already has a lot of stuff he's working on so I was hoping someone else might take a look. Uploaded a .rar of several models from the "chara" folder. They are in .cat and .gtf format.

I tried to learn making BMS scripts since I was localizing this game to English, still haven't finish though but here's the noob script I've made

Code: Select all

not sure if this is the latest script and haven't fully tested it yet since I'm focusing on the game's script and another game now and I also don't know how the file naming Random T Bush script would accept, I just made a BASENAME+0000+EXT as a file name. BTW there's a GTF to DDS out here, I could link it here if you haven't found it yet.

First off, big thank you for the script. Seriously. It extracted the files but didn't work with RTB's script. I thought that the reason the files your script kicked out didn't work was because there were 3 parts whereas for previous Tamsoft game scripts, they kicked out a single file. I had a reply typed up stating as much when I thought to try combining the 3 files. Unsurprisingly, it didn't work either as combining through the command prompt is for text and binary files apparently (thanks google). But my futile attempts at being smart finally led to understanding a comment RTB made about the .cat files. "you can just crop the files to the "0dmt" headers ". I looked at the files your script kicked out in notepad plus and noticed they started with "0dmt". I then opened the .cat file and found "0dmt", deleted everything prior to the first result, saved as .tmd (the format his script uses) and tried importing. It worked, correct weights and all.

TL;DR: Apparently all a script needs to do is delete everything prior to the first "0dmt" header?

As for the gtf files, I noticed not long ago that noesis reads the gtf files just fine so we're good on that front

I feel a bit like an idiot for not figuring it out sooner. Though I still don't know how to make a script do that.

EDIT: I forgot to mention that your script is still useful. There are .cat files that are archives of .gtf files which your script extract just fine.

oh, so the 0x to 0x3 (0dmt) is not needed? I really got no clue since I have no idea about game models and translating the game does not require me to modify the model files. I just made the extractor for get a proper look of the files inside the cat.

Though I'm interested on the Bar Macaroon sign board inside the game since I can't find it in any of the GTF to edit the image and was thinking maybe it was a model file. So might check the models now, and thanks for the heads up for the model viewer!
