Necro posting some things I've found in these battles. Made a handy little trainer to play around with war battles.https://onedrive.live.com/redir?resid=A ... hoto%2cpng
The value the OP wasn't sure about, being a sprite edit, is actually the unit's attack type. E.I.
801B4934 = Riou's unit attack type
00 = 1 range
01 = bow (2 range)
02 = magic (3 range)
There's a second chunk of data in each battle too.
1b7790 = Riou's X pos
1b7791 = Riou's Y pos
1b7792 = Unit heroes 3 bytes
1b7795 = Health 00=full,01-04=up to four swords
1b7797 = status 00=not here, 01=alive, 02 = dead
1b7798 = turn 01=done
Love these little war battles. I'm not sure what hasn't been discovered by this community yet, but I might be digging into the mechanics of attacks.
