While the PSP version contains a GMO file which contains the entire stage/models which Noesis alone can manage, PS2 version differs in the file structure. You can find the PSP models in VGResource site, but you can't find the PS2 models (better quality version). Tools like DragonFF plugin for Blender doesn't work.
DFF- Contains static model's geometry and texture info.
BSP - Contains static world geometry and texture info.
SEQ- Material List
TXD- Textures Pack
