Yes, Ds games work with the Dsi as well, but not Game-Boy games
yes you can its still the same
DSI's and DS (Lite)'s use the same games, so if there's a Yu-Gi-Oh game for the DS, then you can play it on the DSI.
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)
The same way as Ds lite
No, you can't play GBA games on DSi, only DS and DS Lite.
Of course cause they are like the same thing except of the screen, camera, internet, and voice recorder. so you can use your DS lite games.
No, the DSi and the DSi XL both have different plug-in holes in the side from the DS Lite, and so they cannot use the same charger. You figure that out after you sleepily try to use the wrong charger a few times.
No, the DSi uses a different charge to the DS lite.
Yes, they sell some stuff that says compatible with ds, dsi
No, the DSi charger is different than the DS lite charger
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.
YES!!! well, all but those that need the gameboy slot.
