MoT, the only LttP-type battle system is the one I used. You can tweak it to your liking, but if what I have isn't what you're looking for, then I can't help you. A lot of other people have been asking me if they can use my battle system, and asking how I did it, so I guess one of these days I'll post a tutorial or something. Or even better, release a short, simplified version as a demo game that can easily be tweaked to suit anyone's needs, including notes and stuff...
It's not like I did anything revolutionary... I just used what RM2k3 supplies you with. Anyone can do that. I mean, if I could, anyone could.
