A DSi uses DS games.
no
No, you won't be able to do that unless the game/DSi you trade in are very recent games or limited edition/new.
Yes it can.
Go to Nintendo DSi Shop. There will be games where you have to trade in DSi Points for the game and there are some that are free. Just click on the free game and click download.
=I think that if u trade the DS lite & 7 games in you will get £120.00...=
Possibly. It depends on the store.
no but you can connect to the wii to trade stuff etc
At Gamestop if you trade your DSi for a DSi XL you get $80 off the DSi purchase($189.99). If you trade your DS Lite for a DSi XL
You cannot trade downloaded games such as DSi ware. The only way to do so is by using a system transfer from one DSi XL to another one. However, the original DSi XL will delete all data in order to transfer the data to the second DSi XL.
Probably not. Only if you get a really bad quality 3DS or if you sell some games for your DSi aswell.
You can Trade a DSI in at Gamestop, they will give you credits for your DSI to buy something else, such as a 3DS.
