no
The Nintendo 3DS will be able to play Nintendo DS and DSi games but games published for the Nintendo 3DS will not be compatible with those systems.
It is compatible with all DS games apart from any that require Slot 2, which the DSi and the XL do not have. (There is no such thing as a DSi XL specific game.)
No, Pokemon Black and White are compatible with all versions of Nintendo's DS line.
No, it will not be, because it will use cartridges rather than discs. However, there is hope that there will be digital content available through the console, so that we can still play older games. You won't be able to play Wii or Wii U games directly and it's still not confirmed if certain games will have backwards compatibility if bought digitally.
yes you can its still the same
You can buy games from the built-in DSi Shop using Nintendo Points. You need a compatible Wi-Fi Network, though.
The company that manufactures DSi games is Nintendo. Nintendo is the sole owner of the Nintendo DSi console, and is the only company that distributes legal DSi games.
no.....
It downloads games at the Nintendo Dsi shop channel
No, the Nintendo DS charger is different than the Nintendo DSi charger.
Yes, the Nintendo DSi can play Nintendo DS games. The NDS and NDSi are compatible with each other and can link for multiplayer as well. There are really no such thing as 'DSi games' except for DSi-ware and one or two games that require the DSi camera, none of which are compatible with a DS. However, since the DSi has no GBA slot, Game Boy Advance games and DS games that require this slot (e.g. Guitar Hero: On Tour) cannot be played on a DSi. Flash carts and unofficial hardware won't work either, but there may be a newer version available, designed for the DSi. Another problem you might find is that if you have any Wi-fi capable games, they will only work with a WEP security enabled network (or of course a network without security), not WPA.
