Final Fantasy 3/6 offers normally 4 types of treasure chests:
* Item
* MiaB
* Gold
* Empty
This patch adds 2 new types of treasure chests:
* Rare Item
* Esper.
It even handles the increase of the number of Corals when that Rare Item is taken out of a chest. However, none of the chests are modified so if you want to enjoy this patch, you will have to modify the content of the chests yourself. Details in the README.
N.B.: Apply this patch to an unmodified FF3 v1.0 headerless ROM.

Description:
FF6 offers 4 types of Treasure Chests:
* Item
* Monster-In-A-Box!
* Gold
* Empty
--------------------------------------------------------------------------------
What this patch does:
It adds two new types to this list:
* Rare Item
* Esper
--------------------------------------------------------------------------------
How to use this patch:
Out of the box, this patch will seemingly have no effect. To use it, you must
modify the types and contents of treasure chests. The data is located at
ED/8634. Each treasure chest is composed of 5 bytes:
* Its X coordinate
* Its Y coordinate
* The location of its activation in the RAM
* Its type
* Its content
The accepted values for the types are:
* 0x80: Gold
* 0x40: Item
* 0x20: Monster-In-A-Box
Plus the newly added values:
* 0x10: Esper
* 0x08: Rare Item
Now, for the content byte, the accepted values are inclusively:
* 0x00 to 0x1A for Espers
* 0x00 to 0x13 for Rare Items
NB: If you choose to put Coral in a chest, it will also increase the internal
counter of your totals of Coral by one. Like in the original game, there is no
current way of knowing the current quantity.
However, please note that the address in the RAM dealing with the number of
Corals is shared with the value of Cid's Health. Both are located at $1FD0.
In vanilla, it doesn't matter since both events can never interfere with each
other. So, if you want to put Corals in chests for some kind of treasure hunt,
for example, you will have to modify the events that touch that value.

v1.0 - July 25, 2021
Initial release.
v1.0.1 - July 26, 2021
