Question about startropic on the wii’s virtual console(originally on the NES)?

Im on chapter 3, the part where you have to get the fortune tellers crystal ball. In the ghost town theres a grave with the level where you would find the crystal ball. The problem is one part I have to get this thing to see the badguys in order to kill the badguys. When I get the thing to see the badguys it doesnt go into my items box it seems to just disapear so I cant kill the invisible enemies to get to the next area. Anyone have any clue why this is happening?
The thing I get is called the Rod Of Sight…only thing is it doesn’t appear in my items box and I can’t use it

Don’t forget there is another menu screen… for your magical items you need to press Start (the +) and down.
