Buy the game.

There are people out in the world who can't afford games. So, when using emulators and roms, try going to www.doperoms.com or the best website for emulators of all kinds of game systems and games would be www.emuparadise.org to find better Pokemon White 2 game roms. Also check your pc or computer to see if it needs to be cleaned out or extra stuff that harms your computer to be deleted. That also has an affect on roms and emulators which is a possibility your game isn't having a day time. To get started getting your mac, pc, or computer faster, go to www.tune-up.com/Computer-Clean-Up. That should help.
