I'm looking for the guy who ripped these Guilty Gear sprites.

[Ultimecia]

To rip the PS1 game you might try using epsxe and the psx-vram together, but it IS going to be a long and hard project. You can also try to record your gameplay in high quality and clean up the sprites, but it's going to be a hard work and might not be exact. I think some guys from mugenguild or mugenbr might be able to help you
