Extrating models from other games

Ok, I am really tired of all the Digimon Nazis on here, so I want to know what I can use to extract the models from Digimon Rumble arena and what program I’d need to make them ragdolls and what not.

Also a download link for Digimon Rumble Arena would be nice.

uhhmmmm use sorce SDK maby you can do it from there or convert them to gmod format with a program online…
