Note: This page pertains to Reverse Engineering of Okami File Formats.
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.
