Ripping shining tears and wind PS2

Hi,

Im trying to rip sprites from these 2 ps2 games: Shining Tears and Shining Wind, both from sega and very similar graphics.

I tried 2 aproachs:

First, trying to rip the sprites directly from the archives, I extracted some files from Shinig Wind and ended with a lot of .RAX, .ADX, .SFD, .BRA, .TXR;Browsing then with GGD and others tiles views I couldnt find any graphics.

Second, I tried the hard way, playing the game, taking screenshot with some apps, cleaning in a picture editor, but the emulator (Pcsx2) aplies a blur in all imagens and I cant get a clean screenshot, even if i disable all filtering, anti-aliasing, etc.

Somebody can help me?

Thanks

Diego
