That is the sum of our knowledge on the move animations. Hope that helps.
Now, I haven't tried this (can't right now, procrastinating on studying for school atm), but can't we easily view the animation routines with VBA-SDL-H? I'm assuming that would make things a crapload easier to make custom animations. If I recall correctly, VBA-SDL-H has a function where you can decompile thumb routines if you know the offset.
I'm assuming this is what Pokemon Vega did to create nearly flawless animations, and this is what I'm planning on doing in the near future (if it works)
EDIT: Just remembered, regular VBA has a function to view thumb routines, while VBA-SDL-H lets you view last executed thumb routine
EDIT: nevermind, just read JPAN's post in the battle script thread... so apparently it is a scripting language?
