PS Vita GXT to PNG conversion

[WinkelHime]

I extracted CG files from "Eyuu Senki" PS Vita version, but they are in ".gxt" format.
Need help to convert them in png ( tried GXT Converter and Neptunia/Senran kagura gxt sripts for Noesis, no use).

elif texInfo[8] == 0x85:
#texFmt = noesis.NOESISTEX_DXT1
texFmt = noesis.NOESISTEX_RGBA32
texData = rapi.imageFromMortonOrder(texData, texInfo[9]>>1, texInfo[10]>>2, 4)
texData = rapi.imageDecodeDXT(texData, texInfo[9], texInfo[10], noesis.FOURCC_DXT1)
texData = rapi.imageDecodeRaw(texData, texInfo[9], texInfo[10], "r8g8b8a8")

Code: Select all

elif texInfo[8] == 0x85:
	#texFmt = noesis.NOESISTEX_DXT1
	texFmt = noesis.NOESISTEX_RGBA32
	texData = rapi.imageFromMortonOrder(texData, texInfo[9]>>1, texInfo[10]>>2, 4)
	texData = rapi.imageDecodeDXT(texData, texInfo[9], texInfo[10], noesis.FOURCC_DXT1)
	texData = rapi.imageDecodeRaw(texData, texInfo[9], texInfo[10], "r8g8b8a8")

where is the elusive Noesis script that this goes into?
it doesn't look like it belongs in this one

edit
okay since no one is linking their sources i made a new Noesis script with chrrox's info to open these samples
*updated Nov 18, 2016*

tex_EyuuSenki_PSVita_gxt.zip

don't think those dimensions are correct for that image in chrrox's post,
1024x1024 seems to support the image data better

Good progress.
For reference, thats how it should look like.

How did you extract resource from PS Vita? I know about henkaku, but I can't decrypt resources on game which I wanted.

I don't own Vita personally so have little knowledge about actual process. Got ready to extraction game files by my source.

I wrote a GXT importer for Noesis about 2 years ago, for my own personal use, because Vita content wasn't really public at that point. Since people are leaking things all over the place, I figured I might as well enable it in the latest release, so it's in Noesis 4.2. It will handle these GXT's, as well as probably any other GXT on the planet, including correct PVRTC 1 & 2 decoding. Its PVRTC2 decoder is actually the only hardware-accurate one in existence that I'm aware of - the PvrTexTool and SCE libs both handle the palettized block mode incorrectly, which produces some subtle flaws that you won't see on hardware. So that's something to keep in mind if you've been using a makeshift solution by changing the block ordering in order to shovel these things into PvrTexTool or something.

So, enjoy. By the way, the issue with your script here was that tiled data on this hardware will always be padded to a power of 2, so it's correct to pad to the next power of 2 when not dealing with LINEAR/LINEAR_STRIDED data.

okay i know Noesis has native support for gxt now but i wanted to fix the python script for
completion's sake. i updated my previous post with the updated script so it read the width and height
and will round them up to the next power of 2 so they look correct.

Hey uhm, I'm having some trouble with a specific gxt file, and it seems to be recurring in a few. It throws the error 'an integer is required'?

it works fine with Noesis native plugin, don't use my script because it
was made to work only on the samples in the first post (type 0x85)
