Wind Waker in progress

[Drakmyth]

My friend is working on a Wind Waker game. Only a couple glitches are slowing him down. The only one that comes to mind are the invisible enemies. All flags say that the enemies should be visible but they aren't. Does anyone know why this is happening?

Do the enemies have sprites assigned to them?

[Drakmyth]

Yes, the only sprites that have been edited (we are using normal monsters, not ones we made) are the Link sprites so that the first link doesn't have a shield. (Because there are only two shields in WW.)
