This request is basically for a firing noise for every enemy in the enemy editor. (i.e. overwriting the default weapon spawn noises, and also allowing a sound for throwing arrows and swords). This is different from the enemy's ambient noise.
A few enemy classes would have this changed to be different:
Keese/Peahat/Phantom Ghini: Sound played while flying (i.e. not halted)
Rock: Sound played upon impact with ground
