I am sorry to tell you this but no, a dsi cant fit in a ds case.
You cannot find your DSi with a DS
You cannot find your DSi with a DS
yes you can use Nintendo ds games in a dsi
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.
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)
No, the DS and DSi use the same cartridges.
No, the DSi uses a different charge to the DS lite.
you cant use the 3DS charger for the DS/DS Lite, but you can use the 3DS charger for the DSi and the same with the DSi charger, you can use it for the 3DS.
No but DSi can play DS games.
No these are only for the DSi. If they were compatible with the DS it would just be called a DS game.
Na, You Just Need A Ds, A Ds Lite Or a DSI
No, the DSi charger is different than the DS lite charger
