Did Fusajiro Yamauchi invent the Nintendo DS?
The Nintendo DS (ニンテンドーDS?, sometimes abbreviated to DS or NDS) is a handheld game console developed and manufactured by Nintendo. It was released in 2004 in Canada, the United States, and Japan.
Nintendo shrinked the guts of a regular Nintendo DS and shoved it in a smaller shell, improved the ability to change the backlight intensity, changed the power cord, moved around the power button and stylus slot, added more stuff in pictochat, and improved some DS flaws, then called it the DS lite (for its backlight ability and possibly for its light weight).
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.
