ds lite importion

Would there be any downsides to importing a Japanese DS lite? From what I can tell the battery charger is compatible here, and the games seem to be region free. Does anyone know about the wifi compatibility, or how homebrew works with jap firmware? Or if I'm wrong about the power/games? I'd hate to drop 200 bucks for it and not have all the features a domestic one would have.

why would you import things that are guranteed to come here?

they don't go removing stuff from stuff for american release unless you're dealing with ecsessive culture shock, or hardware that did better in japan (like the e-reader)

what makes you think ANYTHING form the jap DSlite will be missing from the US DSlite?
