Rather than C/P my own tutorial again, I'm going to link to this page instead:

EDIT: Sorry about the previous video, it didn't held my quality standard, yet uploaded it anyways.
This one is much better and doesn't chop half the frames (most notably Extrasensory's animation).
/EDIT

Fairy-type in action, nothing too fancy:

Welp it's pretty neat (as you did with SS) but there isn't much in it for the momment.
I think the main problem with this kind of mod is that it would require to create new moves to handle ones like Moonblast. As I'm not really in Pokemon hacking, I have absolutely no idea about if you can even make this.
Anyway I wish you luck with this!

Adding new moves is on a whole another level, look at this:

See how it is volatile?
And even then this is only partial (like the Fairy-type BTW)
Well Gen V code is overall a tougher nut to crack than Gen IV, so no surprise here.

About new moves, hmmm… how about giving a new life to moves that could be easily forgotten otherwise?
Like I did on my SS mod, for example I would turn Extrasensory into a Fairy 90 BP move with 20% chance of flinching instead of 10.


Thanks for the encouragements, it really is appreciated
