MST Files

[VPGx]

Working on a project remastering an old game. Metal Arms: Glitch In The System was available on Playstation 2, Xbox (Original) and Gamecube. While we have the .MST files (containing all the stuff we need) we are unsure on how to get the materials. We have all sounds done however we are trying to figure out a way to get models and textures without having to use 3D Ripper every time we load into a new section. Any help is appreciated. Thanks.
