I recently saw the list of the many uses for boss flags, one of them being events. This is definately a handy use for them, but one thing bothers me, when Link returns to an event-branching room (with the invisible fire enemy and hidden warps), the secret SFX goes off, which is slightly annoying, and since the identical room which Link is warped to doesn't play the SFX, it essentially reveals what is happening behind the scenes.
Thus, my question is, is there any way to force ZC to not play the secret SFX?
