Move the arrows to bag and select in w/ A. move arrows to get to pokeballs, select the poke ball w/ A. f you've weakened to Pokemon enough you may have a successful capture!!!
There is no such thing as a %increase by pressing buttons while the poke ball shakes. people do so because it gives them a false sense of confidence .

^^^HAHA so true. Made me laugh out loud. But, I did read on a help screen in one of the games that pressing L and R as the ball sways in the corresponding direction will help catch it. But if that doesn't work, then get better freaking pokeballs and stop whining on this website!
