Vertical guardians shouldn't collide with items in MM
(they certainly don't in JSW, but I haven't actually
tested this in MM), because they are drawn before items
(an item can collide with a white-ink guardian and
get collected, though).
However, Eugene /can/
collide with items (killing you) because Eugene is drawn
*after* the items, and so can collide with their pixels.
Eugene is not technically a vertical
guardian.

Poke the number of pixels to move the conveyor
animation down by into the least significant three bits of
Offset 625 (which has the format 0111Yyyy - see my Manic
Miner Room Format,
http://www.cs.man.ac.uk/~broada/spectrum/willy/format.html#conveyor target=new>http://www.cs.man.ac.uk/~broada/spectrum/willy/format.html#conveyor> ). I would do this *after* editing the conveyor
animation in MMSE, as it might upset MMSE if it sees a
value other than 000 for those three bits.
