The shape and size of the DSi game card is exactly the same as the original DS games
No, a DSi is not powerful enough to run a 3DS game, and 3DS cartridges are specially shaped so they will not fit into anything but a 3DS.
No, DSi points are like money. Once you buy the game, the points are gone. (You still own the game, even if you remove it from the DSi. You can go to the DSi store and redownload it for free. )
a dsi is the game system and dsiware is like software and games for the dsi. you have to buy dsi points cards to get dsiware.
No
Nope.
It looks the same as a DS game card, and you can also play your normal DS games in the DSi.
You can get them from game stores like GAME or Gamestation. Remember that there's no such thing as a 'DSi XL' game, they are just 'DS games', though there are a handful of games that only work on DSi, there's none that are XL-only.
The 3ds supports all DS, DSI, and 3DS games. Like the DSI, it no longer supports game-paks for the Game Boy Advance.
it is like for example a dsi
No I don't think so
There are no Dsi game chips but there is a bakugan battle brawlers game for ds
Yes it is. I have the game, a dsi, and the game works with it.
