PS2 "Swizzled" Textures & Color Palettes

[Fireboyd78]

[B]Update 6:45pm: Figured it out, nevermind![/B]

[U]Cliffnotes at the bottom, otherwise, here's the long version:[/U]

I was wondering if anyone here has experience with swizzling/unswizzling textures that may or may not originate from a PS2-platform game. The swizzling/unswizzling part is already taken care of, but now I have to figure out how to incorporate color palettes. This is where things are getting a bit tricky for me and I do not know how to continue from here.

Here's what I get when I unswizzle an image (this is an older image and has junk at the top):

Through WAYWO, I found out about the indexes into the color palette:

So basically, each "pixel" represents an index to a color in the color palette. In order to be able to use the palette information, I used [B]Console Texture Explorer[/B], which allows me to accomplish this:

I put some notes in there in case it's needed.

Here's 1024 bytes of the palette data:

They look a lot like floats, and 1024 / 4 = 256. So there's 256 floats, or in other words, 256 color entries. But how would data for RGBA be inside of a float value? You can probably see why I'm really lost.

Is there anyone that can help this clueless bastard out? I wish there was more documentation regarding swizzling, but I just can't find any.

[B][U]Cliffnotes:[/U][/B]
- Format provides offset for texture and palette data (amongst others, see image above)
- I can unswizzle the texture data, but don't know how to parse palette data
- Palette data seems to be a list of 256 floats
- How can a float value hold RGBA data?

Sorry for the long post, just didn't want to leave anything out.

They're most likely not floats.

I actually just found out a possible decoder:

[url]http://code.google.com/p/puyotools/source/browse/trunk/PTImgLib/VrSharp/Svr/SvrPaletteDecoder.cs?r=93[/url]

I'm going to see if this is what I'm looking for.

[B]Update:[/B]
Yeah, that did it:

Needs a few minor tweaks, but I read the palette!

I will update the OP when I get back. At least I finally figured it out!
