Replace Moogle Suit with Shadow Suit

Did somebody say event code?! I can finally help!   You'll want to edit the event that's already in place to show the tombstone text.

Code:

Original Event
C1 B4 01 B0 01 B3 5E 00 - If you're not facing up and pressing A, do nothing.
4B 45 88 - Display dialogue "Here lies Shadow" (Assuming this is unchanged in General Leo Edition)

Added Stuff
C0 A4 00 B3 5E 00 - If you're not in the World of Ruin, end event here.
C0 YY 8X B3 5E 00 - If you've already seen this event (Event bit $XYY), end here.*
80 9F - Add "Moogle Suit" to your inventory
4B YY 8X - Display dialogue $XYY (whichever one you choose to use, in hex).
FE - End Event


*So for event bits, you have to use one here. Otherwise the player could get infinite shadow suits. You can get a list of event bits from the documents section. Find one that is unused. Best way to see if it's unused is to add it to this event, load a completed game file, and then try to play this scene. If you get a Shadow Suit, then it was free.

On second thought, you could place a treasure tile on top of the flowers in front of the grave, or on the tombstone itself. This will accomplish the same purpose, and is much, much simpler.
