Yet another update: Updated script to make use of ps_lz77 decompression in 0.7.5-0.7.6a. Edit line 23 to set your platform. Comment/remove lines 152 & 155-161 if using in 0.7.7 . No reimport.

A small find for 3rd group: going in-game and looking at Gallery, it looks like there are DXT-ish compression artifacts and compression ratio seems to be 4:1.

this is what i see
sample 1 is 142x212 bgra8888 with 28 byte header, imgFmt at 0x0C (00 40), width at 0x14 and height at 0x18
sample 2 is 1920x1312 bgra8888 with 16 byte header, imgFmt at 0x00 (00 40), width at 0x08 and height at 0x0C
sample 3 is 3728x1088 dxt5 with a 28 byte header, imgFmt at 0x0C (00 20), width at 0x14 and height at 0x18
i'm not sure about sample 4 yet, will have a better look later. imgFmt at 0x0C (00 10), width at 0x14 and height at 0x18

Acewell, thank you.
After some brainstorming myself I too understood that Group 3 is DXT5.
Here's the DDS file (I think it's correct) of that sample.

Group 4 may be 1920x1088 DXT1 files...

my concern about 2s001.tex is the height in the header isn't matching the displayed image, as if the image data was truncated or something. it looks cut off in both Noesis and TextureFinder.
The sample 4 files could be dxt1 i guess, Bg9998.tex is all white and Bg9999.tex is all black except for two small spots.

I can make a script for Noesis that will open your samples on 2 conditions, they have a .tex extension and are already decompressed.
Noesis is capable of decompressing them on the fly but this level of scripting is beyond my experience level.
the fmt_bulletwitch_cpr.py script has an example of that and there is Noesis tutorial for Zlib here
http://forum.xentax.com/viewtopic.php?f=29&t=7813

the compressed textures header look like this to me
4 bytes - magic (ZLIB)
4 bytes - uncompressed data size
4 bytes - compressed data size
start of compressed data

Uh, whoops, I forgot to mention that it was cut with filecutter.bms because it was too big to upload, even zipped. It's real size is 10?076?176 bytes, deflate-32K-128word compresses it to 2?717?258.
Sorry.

here try my Noesis script


supports rgba8888, dxt1, dxt5
works only on uncompressed textures.....for now

Acewell, again, thank you. ;)
Meanwhile, I made a BMS script that recreates DDS header from .tex header with "Texture " ID. I will add .tex w/o that ID soon, ZLIB'd - SoonT (once I understand how to do it all inside one BMS script).

UPD: all .tex should be approachable now.

Turns out there's more hurdle: custom LZ77 BGRA8888 pixel data, which is, apparently, typical for Japanese PS3/PSVita games and their ports to Windows. I've found that someone already cracked into it (that C code seemed awfully familiar), but the decompression itself is in inline ASM and I can't read ASM.

UPD2 (2016/05/09 14:38 UTC): bit flags go first (the size of this part is 1/8th of the bulk, give or take 1B), then the bulk of compressed data, then dictionary, maybe?

That was a specific implementation of LZSS. I hope I've commented the lines enough for people to understand.

UPD2 (2016/06/11 15:12 UTC): this seems final...
UPD3 (2016/08/07 11:21 UTC): updated the message a bit.
UPD4 (2016/08/10 18:56 UTC): moved everything to OP.

Hey, I just ripped game tex file from PSVita.
But I dont convert tex file.
here is a tex file from vita version
Someone can analysis and make script?

Suprisingly, I didn't even change anything in my script.
Can you provide more examples, "Obj0__.tex" etc?

Yeah I can extract some Vita's tex file. but color is different.

this is screent shot of Vita version,but extracted vita's file's color is different(town1.tex)

Do you know what is wrong?

and I found some of Vita's file cant convert(but PC's can convert)
ex:FontGp_data.tex
(Vita)

(PC)

I think I got it. Maybe.
Issue #1 was different channel order (PC textures were BGRA, provided PSVita texture is RGBA);
Issue #2 - I've added a dirty 4bpp grayscale texture support.

Please test and, if possible, report.

Thanks! I can convert!
and Is it difficult to reimport? I try reimport.bat, but both of your scripts doesn't work for reimport.

One more, do you convert this file? (PC's FontMes_data_rg.tex) I cant convert it(but Vita's same name file can convert.)

thanks!

Sorry, it's impossible to reimport. I'm a newbie - I focused on extraction.
Try this to extract that PC "FontMes_data_rg.tex" character map you've attached.

Hi,

Can anyone please give me a script to convert the attached .tex images to dds (or png) and from dds to tex.

I can pay anyone who wants to do it as job.

Thanks
