gxtconvert's Introduction

GXTConvert

GXTConvert is a somewhat rudimentary converter for GXT-format textures used by games for the PlayStation Vita. It is written in C# and based on the .NET Framework.

Maintenance Note

GXTConvert is currently only receiving limited maintenance. Please see the Scarlet project for a more generic set of libraries and a sample converter application to convert various game or console image formats to PNG, including GXT.

Requirements

General
.NET Framework 4
Compilation
Visual Studio Community 2013 (or higher)
Usage
Compatible files to convert

Usage

Syntax: GXTConvert.exe <inputs ...> [options]

<inputs ...>: Any number of files or directories to be converted, separated by spaces
[options]:
--output | -o: Specify output directory
--keep | -k: Do not overwrite existing output files

Example: GXTConvert.exe "C:\Temp\GXT\files\" "C:\Temp\GXT\testfile.gxt" --output "C:\Temp\GXT\output\"

Games

Games known to use the GXT format include:

Danganronpa: Trigger Happy Havoc (*.gxt) ⁽¹⁾
Danganronpa 2: Goodbye Despair (*.gxt) ⁽¹⁾
Danganronpa Another Episode: Ultra Despair Girls (*.btx) ⁽¹⁾
Digimon Story: Cyber Sleuth (*.pvr)

⁽¹⁾ Require dr_dec decompression script by BlackDragonHunt for most files; some .btx files are not GXT
⁽²⁾ Packed in *.ftx containers
⁽³⁾ Packed in archive.pk container; requires QuickBMS script by chrrox to unpack
⁽⁴⁾ Packed in OFS3 containers; requires QuickBMS script to unpack

gxtconvert's Issues

FTX File Container

Hello, sorry for being a nuisance, but I'm totally new at modding game files, so I'm here to ask for guidance/help to edit .FTX at Muramasa Rebirth, I'm translating to spanish, to do so in a full-fledged pack, I need to edit those along with .MBS files.

Here are some examples at the folder /_US/GUI: https://mega.nz/#F!MvhlVQID!qCVohVVfFg_kLgpZeGS8_w

Thanks in advance and sorry for my bad English!

GXT

Hi, I would like to ask a question.
Analyzing the format of the game, I came across a texture format GXT.
I decided to take advantage of your utility. But it does not work with all textures, with only a few. I do not know what it can be connected, but some of it converts so good, but some textures convert with errors like "out of range of array". Samples are included.

Steins;Gate 0 GXT support

Can you add support for bg files and character files?

Error when converting GXTs from Danganronpa 1.2 Reload

I don't know if it's an error or not, but when I drag and drop a gxt file to the exe, it gives me a message saying "Exception: Index was outside the bounds of the array.."

thanks，I want to know the PNG how to convert to gxt

Ebikore + Amagami GXT error

This program encountered an error when it's trying to convert.

Here's a sample.

Reverse implementation

Would it be possible to add the option to convert the opposite way (PNG->GXT)?

Suggestion: Add .tga export support

The DR PC ports use tga instead of gxt and I'm trying to back port some stuff from DR2 Vita to DR1 PC, so yeah

Works, but looks like not fully for this gtx from psv

Can you look and help? It gets 1 texture, but i think that it's have more than 1 in 1 file

3d textures support?

I have successfully extracted PsVita's Criminal Girls images/textures. (I'm already translating it into spanish, but I need to update the font and some textures to get a proper localization). It doesn't use gxt directly, but a custom format "imy"; that mixes a non-standard compression with swizzling for power of two textures. I have managed to determine the compression algorithm and to create a decompressor.

Most textures are normal 2d power-of-two textures, and I converted your PostProcessing.UnswizzleTexture to kotlin and works just fine decoding them.
But some textures are swizzled and have a size that is something like 2048x512. I suspect this is instead a 512x512x4 image. And decoding with 2048x512, causes 3/4 of the image to be empty.

I don't have too much experience with Morton, but if I can remember right, the xbox 360 sdk had functions for translating swizzled address/x/y/z with 3d textures, but won't work directly for psvita as far as I know.

So do you know how to implement the 3d lookup?

Example of texture working fine:

Example of texture 1024x512 that is cut.

Font is cut too (2048x512) (font is white so it won't be displayed on a white background):
