The 3DS XL came after the 3DS.
Yes no metter what 3DS is a 3DS
There is no such thing as a 3DS DSi.
No, it is not out for 3DS.
You buy ds or 3ds games and then put them in your 3ds.
yes
No, It's for both 3DS and 3DS XL. 3DS XL is just a larger version of the 3DS.
Basically the 3DS XL is a larger 3DS so if you want a larger screen size, go for the 3DS XL. The 3DS is cheaper and is smaller if the XL is too bulky for you.
yes the 3ds. But if you play for 2-4 hours long with 3d mode you'll get blind. The 3ds is 200-300$ it has 2 cameras and a scratch pad to draw on your picture. And you can make flip notes another thing for entertainment for fun. It's now 150 though. But i suggest that if you have the DSI don't get the 3ds. there's no difference except 3d mode
No, you must have the original 3DS with the ambassador program. The only way to transfer the ambassador games to the 3DS XL is by doing a system transfer, from the 3DS to the 3DS XL, which requires both systems.
In comparison to the 3DS, the 3DS XL is much larger with a bigger screen. The 3DS games work just the same in both consoles.
There is no DSI 3DS comming out, the 3DS has DSI features and the 3DS is the new version of the DSi but, remember the 3DS is 3D, Seeing is believing.
