Two updates in one day, yay!
After giving it some thought and trying my luck, i found a way to put Zohar's hokuto no ken 9000,77 face pack to good use.
In-game now Juda, Mr. Heart, Raoh, Shin, Thouther and Toki will have their face icon change accordingly to their palette, in addition to Kenshiro, Mamiya and Rei.
The only one left is Jagi, since Ts's color order doesn't match Zohar's face icon. drowin's and ahuron's however, work well. It's a darm shame that their Jagi is rather crappy...
