Tales of the World: RM models

Hihihihihhi.
Okay! I've been ripping models from Tales of the world: Radiant mythology for a while now.
I've posted some models. I have been using JPCSP for the models though. 
I have been wanting to extract the files from the actual ISO so today I did.
My issue is actually opening the files though.





Here are images of the files.
They mostly consist of Arc and bin files.
I used an arc extractor and the files were empty.
Any ideas on how to open the files? 

I can't figure it out. :<
