  • 0x02DA3A = (01) Phase 2 weakness to disable*
*Only one damage table is provided for Wily Machine's weaknesses. However, during each phase of fighting Wily Machine, the game manually ignores damage when you have certain weapons equipped, giving the impression that each phase has different weaknesses. Normally, in Phase 1, damage is negated if you have Air Shooter or Quick Boomerang equipped. In Phase 2, damage is negated if you have Atomic Fire equipped.
