Progress happens slowly sometimes. I know that verts with Z = 1.0f are texture coordinates. Verts with the 0x00003f80 flag seem to be related to normals. Furthermore, verts with 0x0000bf80 or 0x00000001 flag appear to be the actual verts used marked in the above image as green and red accordingly. I already know the PS2 doesn't support quads so the data must represent triangles or triangle strips but I am unclear on how the vertices are ordered in the file.
