In post 1 of Fire Emblem 10 Modding, we delved into the structure of the ISO and locations of key files that we care about. One of these files was
FE10Data.cms, which contains a substantial amount of data that we want to modify.
This post will describe
FE10Data.cms's sub-sections in more detail, as they were brushed over in post 1. It should act as a decent reference for anyone who plans to modify this file.
