Statue combos (Left, Right and Center) shoot fireballs, no matter the state of the "Statues shoot fire" enemy flag.
[699] Statues always shoot fire
This was already fixed (here) after 697; I don't think 699 was a new build of ZQuest or Zelda Classic, only ZCL.
Even then, it wasn't listed on the changelog, so I can understand overlooking it. 😉
Ah, I never saw that. Cool.
