Final Fantasy III: Opened Eyes Terra Fix

"When you first reach Terra in Zozo, she's laying in bed with her eyes open. Then during the conversation with Ramuh, she thrashes around, and the party helps her back into bed to recuperate, with her eyes now closed. However,
should you leave the room and re-enter, even before getting the Magicite or talking to your comrades, her eyes will be open again. This despite her being equally unresponsive when talked to and the party's dialogue not changing."

This patch fix the "bug" by adding an action to NPC $10 (Terra) giving her the closed eyes pose between the time you talk to Ramuh and the time you come back to Zozo after the Magitek Factory. This change is logical with the following argument; Enough time has passed in order for Terra to potentially "recover" and this time is more significant than stepping outside a door and coming back.

The ALT patch is an alternate patch that will make Terra open her eyes when Locke present her Maduin magicite, right after he exclaim himself "Magicite!". This version of the patch is logical with the theory that Maduin Magicite has enough power to wake Terra up because of the bond she shares with him.

One could argue if this is really a bug or was intended by the devs, but regardless if both fixes leave room to a bit of interpretation, exiting and re-entering Zozo room seems a bit quick to make Terra regain strength or get her out from her "coma".

"When you first reach Terra in Zozo, she's laying in bed with her eyes open.
Then during the conversation with Ramuh, she thrashes around, and the party
helps her back into bed to recuperate, with her eyes now closed. However,
should you leave the room and re-enter, even before getting the Magicite
or talking to your comrades, her eyes will be open again. This despite her
being equally unresponsive when talked to and the party's dialogue not changing."

This patch fix the "bug" by adding an action to NPC $10 (Terra) giving her the
closed eyes pose between the time you talk to Ramuh and the time you come back
to Zozo after the Magitek Factory.

This change is logical with the following argument; Enough time has passed in
order for Terra to potentially "recover" and this time is more significant
than stepping outside a door and coming back.

The ALT patch is an alternate patch that will make Terra open her eyes when
Locke present her Maduin magicite, right after he exclaim himself "Magicite!".

This version of the patch is logical with the theory that Maduin Magicite has
enough power to wake Terra up because of the bond she shares with him.

Since the original entrance event is only 4 bytes, the following entrance
event (map $E8 at CA/F008) was moved and started a few bytes forward in order to
make possible a subroutine call for the entrance event we wanted to originally
modify. New and extra code is moved to free space D1/F9D0 and cover $1B bytes.
The ALT patch take $27 bytes of free space.
