Answer to everyone who has this problem

Umm...you need to use HM05 Defog, the animation does not show that is why the screen goes blank.

Get HM05 Defog, There's been a problem with the emulation, After you use defog, if you see grass before the screen turns white walk into the grass until u see a wild pokemone, after the battle the screen turns to normal.
