Item Auto Status, & etc

Is there a patch that give either or both Boomerangs & Maces their own icons, instead of the "Special" icon.

No... there's not a patch for everything ya know lol. Especially miscellaneous things like this. You'll either have to sacrifice another one for it, or look into expanding the icons in order to add more. Adding more is very doable, but I'm not going to get into that right away, unless that's the route you would like to take, but it's not exactly beginner-level stuff.
All the patches we have are here: https://www.ff6hacking.com/forums/forum-15.html
And you can check this list to look for other ones that exist: https://www.ff6hacking.com/misc/dark_mag...readme.txt
There are links on that list to other patch author sites as well. assassin's site has a bunch of patches: http://assassin17.brinkster.net/patches....chor-misc2
and there is one there that deals with Item Icon Expansion if you're interested in that, though it's not going to instantly give you more icons to use - it'll take some more work.
