PS3 3D Model/Texture import?

Hi,
Im trying to import a 3d model file from a PS3 game (Hyperdimension Neptuina Victory)
and i know all character models are on this site but i need the weapons and so i found the files for the weapons but they are a "ism2" file and i have NO idea how to open this type of file or the texture file which are "tid" files any help?

Thanks
