How to unlock Billy and Saiki in KOF XIII GM

They are unlocked in Arcade mode.
For Billy you must complete 2 Target Actions per round, if your character is defeated, it doesn't carry over, so you must complete the TAs again.
For Saiki, you must complete 5 per round.
Difficulty doesn't matter, so you can play on very easy if you want (I recommend this for Saiki, it's much simpler).
Also, you don't need to actually land the attacks, if your opponent blocks, it counts anyway.

What’s the easiest cancel drive for Terry Bogard?

[@filibertogiron]

Burn knuckle followed by crack shoot.

So whats the easiest Drive?

[@Kaimitsu_]

The King drive cancel is the easiest for me, but it depends on who you play.

[@mikaela5938]

is there any character that has easier drive cancels, i have been trying to do dp into projectile with 94 kyo but it almost never comes out

[@EurotuningMty211]

With Kyo, use "Hyaku-Hachi Shiki • Yamibarai" and then "Nana-Ju-Go Shiki • Kai".
That's the easiest way to do a Drive Cancel in my opinion

[@Sin-pt2eq]

K has a really easy one just quarter circle back 3 or 4, and when you see it land just input it again the window isn’t super tight either. They’re not super hard to do tho just remember that you can only cancel on hit
