Shadow The Hedgehog (Gamecube) Model and Stage Ripping?

[Miles Prower (Anti-Verse)]

Recently, i've been looking into the 2005 game, Shadow The Hedgehog for some models that could help with some model projects, but the issue lately is that the files don't seem easy to rip or little information as means to rip it. I've gotten lucky with the .dff files, but no armature in Blender.Another issue is the textures due to their format as well as the extractor I attempted to use didn't work (It was a GTA 3 TXD file opener that I could use to look into the images). If anyone has any clue about them, i'd be happy to listen, but a little warning: I might have to have some things simplified or explained via image. I'm sorry if this is a waste of anyone's time or a burden, but i've got no other answers available to my question or my task. 

Examples of stuff that's been ripped.








(Yes, the models were edited or adjusting by smoothing the faces , but it works nevertheless)
