Ripped level models from Super Monkey Ball JR (GBA)!

[Hiccup]

How does one even rip models from a GBA game?

Doesn't the GBA not have 3D hardware, meaning there's no sense of depth? I assume that means you cracked open the game internally to find these.

I don't think it has 3D hardware, so the game would have to have a special engine for it.
You would probably need to analyse the game data to rip the models.
