==Explanation==

This file describes different zones that trigger things when Ammy enters them, such as: loading zones, triggering events, the ability to examine an object, showing tooltips, or making Issun indicate things.

When describing a loading zone, it refers to [[Exit Destination (.JMP) Format]] for the destination.

==File Format==
===Overall===
{| class="wikitable"
! Start (Byte) !! Width (Bytes) !! Type !! Field Name !! Note
|-
| 0 || 4 || uint32 || header || File extension followed by 00.
|-
| 4 || 2 || uint16 || unknown || Always 00 01 or 01 00.
|-
| 6 || 2 || uint16 || entry_count || Number of zones.
|-
| 8 || 8 || uint64 || padding || Not entirely accurate - all 00 in SCA and SCI, but not in MEH
|-
| 16 || || ZoneEntry array || entries || One for each zone definition.
|-
| || || 00 || padding || Pad for 32 byte alignment.
|}

===ZoneEntry Format===

Describes a single zone definition.

|-
| 58 || 2 || uint16 || effect_index || Only partially known. It's an index into something - on a dialogue, if you change this, something different is said. But is it the flag index or an index into another file?
