Ripping textures from Budokai 1 PS2

[NauJavy]

I wanted the textures of budokai 1 to make the textures as much HD as possible. Call it as if it were an experiment. But how do I get the textures of budokai 1? 

I have searched for tutorials, but I get budokai 3.

Can someone tell me what I need and how to do it if it is not too much to ask?

Well the most common program to use is Game Graphic Studio
