Where this, that, and the other thing are located in the Brawl ISO

[D.L. Yomegami]

For a few future stage projects of mine, I'm looking at some obscure places to find pieces. I've already torn SSE apart (for the most part; see further below), so now I'm seeking to find other things. However, said things aren't exactly easy to find. So, I'm wondering if anyone knows where the following might be located (or if they're even in the ISO to begin with):

1. This version of the FD platform. This is one of the things I'm not certain if it's even in the ISO. At first, I thought it was just a variation rihuganon made to differentiate his/her FD textures from everyone else's. Then someone else used that same platform for his/her FD textures (example) and didn't get called out for not crediting rihuganon. That made me wonder if it was a pre-release version of the FD platform that's still in the Brawl ISO somewhere.

2. The Brawl Intro stage. A bunch of stages use the background of this stage, and looking at their files in BrawlBox reveals their SceneData came from something called "StgOpening." However, looking through the Brawl archive I'm currently using brings up nothing for it, which makes me sort of doubt its existence.

3. The models/animations/what-have-you of several Subspace enemies (especially the Primids). Normally, the adventure stages have this information already contained within them (for example, you can find the model for a Shellpod by looking in the first ARC of stage 290001, Outside the Ancient Ruins). However, none of them contain models for the Primids - including the stages where they make prominent appearances such as the Entrance to Subspace. As well, enemies like the Greap and the Armight are missing their weapons. Since this information has to be on the ISO somewhere, I'm wondering where else it might be located (possibly in an area that hasn't been tapped into yet?).

I know where the Primids are, as well as the trophy stand item, key, koopa shells, stock ball, and that stick-like bird that you can grab after it gets stuck in the ground! They're in the adventure_common.arc file that is in the adventure folder thats in the stage folder, basically where you find the adventure mode stages. It has the Primid model, wepons and its animations. Its amazing how many animations the primids have, they're just a handful animations away from being a full character, they have three waits, walking, ect, they're pretty much just missing specials, taunts, diferent wlkaing speeds, and item-related animations really. I didn't look that much at it, so there's probably more animations that they don't have, and maybe some that I listed that the may have that are unused, like Luigi's second hair, and Giga Bowser's assit item animation.
