How to rip PS2 games

[dragonite474]

@ultimecia: it's from flightplan, it's looks like disgaea series or Soul Nomad & the World Eaters so I don't know how people can rip sprite from those game and I think the method to rip sprite from my game and those game are the same. So can you tell me how to rip disgaea series so i can figure out more about my game. Moreover do you know GGD tool http://www.crimson-penguin.com/GGD.php I cant the link for it, thanks
