You can't
The 3DS transfer tool allows you to transfer DSI games from a DSi to a 3DS.
That is not possible. You can transfer DSiWare games from DSi to 3DS, but not the other way around.
Click on it.
No you do not, as DS games do not rely on or interact with DSi software.
The 3DS can play DS and DSi games, and most DSiWare games will be available for download/transfer from an existing DSi when the eShop launches in June.
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
Club Nintendo coins are only used to redeem gifts and are not the same as DSi points so it cannot be converted.
No. Once DSi points have been bought they are tied to the system they were bought on. There is no way to transfer them to another system.
a real game yes a fake one no
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.
I know the difference between the DS and the DSi the DS you can play GameBoy Advance SP games and the DS games of course, the DSi ( though I don't have a DSi I have a DS ) you can not play GameBoy games on it you can also somehow download action replay cheats/codes which you can not do with the DS.
No, you cannot. Even if you copy games purchased from a different DSi, it will not work. This is because games will only be recognized by the DSi if your system purchased those games (or you had a system transfer). It is recommended to not move files on the SD card around or your DSi may not be able to locate the games and will not work.
