well it does say "The DS Lite is Region Free! You can play games from any region on any console unit."
im guessing it would work regardless.. all you would need is a power adapater thing of some sort to convert the power..
now with that being said.. skinnypupp, the ds lite specs in the quoted link above.. im just wondering when you say it is Smaller and lighter.. is that compared to the recent DS LITES or compared to the original ds phat
