there's a calc style thing there, although I've never studied the extent to which the games use it; that part of the suprnova implementation was given to me and I haven't really touched it (unlike the rest which is almost entirely my code at this point). Apparently it's quite similar to the 3d bounding box collision stuff that brap boys etc. have (which might really be separate from the rest of the protection even there, we'll see once we get an internal rom, assuming we ever do)
that said, no, protection isn't a big deal for any of these.
