The Nintendo DS Emulator is a program that you download off the internet and onto your computer. Then you can download any Nintendo DS game off of that site and play them on your DS Emulator. This is ILLEGAL though (since you did not technically buy it). People do say you gotta Delete it within 24 hours.

Yes
As far as i know, there is no Nintendo DS emulator for anything except Windows and Linux.
Pokemon White are a Nintendo DS game, so look for a Nintendo DS emulator.
Yes. DeSmuME does.
Yes you can.
This is probably because you have a computer that is not powerful enough to run the emulator properly. The DS emulator requires a fairly powerful computer to run correctly.
check the settings of the emulator, there might be a setting for that, otherwise you'll have to buy the game.
