How do I rip Kingdom Hearts 1 worlds and keyblades ?

[Eu Tyto Alba]

So, I've got the KH1 ISO and followed this video tutorial with much success at ripping characters, but what I'm really after are the worlds, inanimate objects, and keyblades, which "khdump" did not catch. I also tried o0DemonBoy0o's PS2 ripping instructional, but when I hit [ Run ], PSX2 0.9.8 just opened a blank gray window. It never even let me select what game I wanted it to open.

I have no programming experience other than my attempts to rip 3D models, so I'm ever at odds with a perilous sea of technobabble. I wade through it when I must, but right now I'd really appreciate if someone could cast me a line.

My intent is to papercraft.
