Hi everyone!
It's been more than two years that I visit this site for translations,and now after some basic hacking into PS2 games (texture and ADX audio) I trying to edit Virtua Tennis DC's shirt textures.

After some Hex comparing I found out that the same texture file I want to edit in this game version for DreamCast and PC, uses the same exact file structure.

For an instance: http://www.zshare.net/download/82258195dd70cf/
This file should contain a single UNIFORM TEXTURE.

As I already used ASF explorer or GameGraphic studio for PS2 to actually display those images, I do not understand this texture encoding.
Are there any tools to extract an actual image file for this?


Thanks for the help!

-UPDATE-

I tried hex filling the bin with 00, and ended up changing all into a black uniform.



However it's just brute force and no array has been found.
I noticed also that if I insert only one FF inside a certain address, one white pixel appears onto both sleeves texture, like it's mirrored to the other side.


Doing so I understood that there is no information of size or compression on the bin file, just plain texture data, probably like this:




So, It could be possible some parts of texture is mirrored to save up space BUT some points. I'm investigating with the bowling suit, which has text on the texture, (thus, not mirrored)if there is a space for inserting logos.

Any help is REALLY appreciated, of course!

P.s. Is there any VRAM WATCHER prog for DC emus?

Quick update:

From 00000000 to 00000009

Is the collar image part, total 5 pixels repeated in pattern (still figuring it out, however..)ENJOY!
Behold the Referee Unit!
