hng64: bbust2 now has 3d geometry. [Andrew Gardner]
NOTES: The geometry is correct in bbust2 (and it's 'playable' - I beat the first stage), but it's missing half of its geo and the textures are wrong. They're close to correct though. I think there are multiple texture page sizes that I'm not taking into account. I just noticed there might be a crash or two still lurking in there as well. Will fix soon.
