Unauthorised devices can damage your system, that's almost certainly what has happened.
You can play ds games on the dsi and you can download games from the dsi shop channel using internet access.
You cannot trade downloaded games such as DSi ware. The only way to do so is by using a system transfer from one DSi XL to another one. However, the original DSi XL will delete all data in order to transfer the data to the second DSi XL.
YES!
No, the DSi can't play GBA games at all.
The shape and size of the DSi game card is exactly the same as the original DS games
Yes, the Nintendo DSi does have its own game cartridges, though they are extremely rare. There are only a handful of DSi-exclusives as they are games that require the camera. The console is also backward compatible so you can use the original DS games.
You can download unlimited, full version Nintendo DS and DSi games and easily transfer them to your DS / DSi using: http://www.squidoo.com/Download-DS-Games
all the games can be downloaded or all of the original Nintendo ds. this is not real
No ... by games I think you mean dsi roms the only way to play dsi roms is by using a flashcart as nintendo thought about this and they blocked playing by your memory cardor internal storage
The original DS can play them, as can the DS lite. The DSi, DSi XL and the 3DS do not have a GBA slot.
well of course the Nintendo dsi has games of its own in the dsi shop. But you have to download then you would get a thousand points. These points u can use to buy games from the dsi shop. At first you have only a couple of games like (4 or 5).But then after you start using your dsi and win points from these games, there will be more games in the dsi shop for you to buy from also have to download the web or (Internet) from the dsi shop.) If you need help please contact me on this email: zainab3729@gmail.com. Thankyou!
The DSi can play DS and DSi games, as well as DSi ware games. It cannot play GameBoy games or 3DS games.
