yes
No you can't use Game Boy Games on the DSi
yes you can use Nintendo ds games in a dsi
Of course!!! The dsi XL is just a bigger version of the dsi.
There are no cartridge games made for DSi, but you can buy games from the built-in DSi Shop, or use the internet browser from the DSi Shop to access made-for-DSi websites like DSiCade.com.
Yes, you can use ds games on the dsi. My friend's sister got one for her birthday and she said you can use them in the dsi. But the Dsi's do not fit in a Ds case.
just use normal ds games
Yes, Ds games work with the Dsi as well, but not Game-Boy games
no. Nintendo dsi are region locked. that means that if you buy a Japanese dsi then it only works with Japanese games
yes. a dsi is the same as a normal ds but with a camera.-------------------------------------------------------------------------------You can use the same codes from the DS to the DSI, but you cannot use a DS Action Replay for the DSI, you have to use a DSi Action replay, which works with all, to get codes for DSi.
No. It is bad because no Guitar Hero for DS and You can't migrate Pokemon.
yes
Yes. Certain games, like WarioWare: Snapped! and Photo Dojo!! use the DSi's cameras.
