All vita 3.60 NIDs of User and Kernel exports

DB Lookup

Overview

This file is a reference database of every exported functions on a PS Vita running firmware retail 3.60.

Why?

This is helpful to create db.yml tools. For example, I can make sure that every NID of the vitasdk actually exists. I can also use this to find the library and module corresponding to functions in a NID list.
