Nothing, as a 3DS game will not fit into a Ds slot. FOr downloaded games you will not see it
No the 3DS game cards are shaped slightly different then the Nintendo Ds. Of course if you could put the 3DS game cards in the Ds lite it would still not work because the features and intense graphics the nintendo 3DS requires for games can't be used on the Ds lite. Don't buy 3DS games for the Ds lite as it just won't work. You can consider buying a 3DS however as the 3DS is backwards compatible with all DS games.
You buy ds or 3ds games and then put them in your 3ds.
Gameboy color/colour games do not work on the following systems (this is because there is no slot to put it in, however on the Nintendo 3DS you can download some GBA/GBC/GB games):Nintendo DSNintendo DSiNintendo DSi/XLNintendo 3DS
Yes, you can
No there is no slot where you can put the game boy sp games
At the top of the 3DS is a slot for cartridge-based games. Insert the cartridge here. On the 3DS' menu screen, typically the second icon on the first column, is the one for the inserted game. Select it with the stylus to play.
From what I know, no. The 3DS games have a something on the game card that doesn't let you put it in on other DS systems. To play Animal Crossing 3DS, you would need to buy a 3DS.
Yeah, I do it all the time. By the way, why did you even bother asking when you could try it out for yourself like I did?
No.
It won't fit in a DS or a DSi, there is a tab on the 3DS game to stop it.
No, you can't.
