Can the touchscreen of a Nintendo ds be cleaned?

Yes, PokÃ©mon LeafGreen will work on a Nintendo DS system as long as it's the original Nintendo DS system that is referred to as the Nintendo DS Phat and the Nintendo DS Lite. The Nintendo DSi, Nintendo DSi XL, the Nintendo 3DS and the Nintendo 3DS XL cannot play LeafGreen because they do not have the Gameboy slot like the originial DS and the DS Lite do.
The Nintendo DS is fully backward compatible with Nintendo DS games; however, the Nintendo 3DS does not have Slot 2, as seen on the Nintendo DS and Nintendo DS Lite, so those features will not be supported. Additionally, DSiWare games will be available to download on the Nintendo 3DS after the software update in May 2011.
