There is no such thing as "DSi Lite" but let me tell you this: at the moment of writing, ALL DS games fit in ALL DS's (DS, DS Lite, DSi, DSi XL)
Yes, the Nintendo DS lite can play DSi games
No, the DSi uses a different charge to the DS lite.
Yes, Ds games work with the Dsi as well, but not Game-Boy games
No, the DSi charger is different than the DS lite charger
No, you can't play GBA games on DSi, only DS and DS Lite.
no, the DSi does not have the game boy slot that the DS/DS lite have
you can trade your ds lite in at game and usually get £75 so you only have to pay half the price for your DSI
yh in game you can trade in a DS LITE and get a dsi for halfprice
no, you can't download game to a Nintendo DS lite, it only works with a Nintendo DSi or a DSi XL
Yes. Most video game shops will do DS Lite->DSi trade-ins, but you'll likely only get about half of what a DSi costs.
Not really, the DSi will be worth more, unless the DSi is in bad condition, and the DS Lite is new. The DSi would have to be refurbished or very used and the DS Lite would have to be new. The game would also have to be a newer game, which would make up the price difference. Now, a DS Lite and 2 new games would match a used and or new DSi.
Yes they do!
