SSB64Edit
It's unclear how SSB64 determines whether something is reflectable or absorbable; in any case there's a decent possibility that it's not part of the hitbox itself. So for now we must ignore it.
SSBMEdit
SSBM special hitboxes have a bunch of unknowns, and even the knowns are a bit flaky in some cases. Best to use the "specialraw" parameter so at the very least things will be easier to update later.
