In FF4 Ultima Iconic, there are a lot of icons used to communicate with the player. In my Ultima Iconic project, I added status icons to the battle messages, so that the negative status icons are seen more often and therefore offer a more intuitive connection to the menu system outside of battle.
Here’s where those data points live in the rom. The above is what it looks like before the icons are added.
