Save data is tied to the 3DS that wrote it, so it should be clarified what you're trying to do. If you want to plainly copy the data from one 3DS to another 3DS, this is not possible. The other 3DS will be unable to use this data as it was not written by that console. If however you mean you want to do a System Transfer and retain the game's save data on the new system, you perform the transfer first and then swap SD cards over, and the new console will treat it the same as the old one did.
No, Pokemon data is still stored on the game card itself, not on the internal memory of the 3DS.
Download copies of any eShop game are locked to one 3DS; even if you insert your console's SD card in another 3DS, the data specific to download games is unreadable. The only way around this would be to initiate a System Transfer, then insert the SD card once the process has finished.
The 3DS memory card is for downloaded games and their save game data. It contains your streetpass data, and you can add music to it too. Photographs and videos you take using the 3DS can be copied to the SD card also.
It has 264 kB of internal memory. It also has 4 MB of RAM. 1 MB is 1/1024 of a GB, 1 kB is 1/1024 of a MB.
You need to physically remove the memory card from the 3DS and add the music to it using a card reader on a PC or laptop.
no. but maybe you can play GBA games on the 3DS with a R4 or a supercard.
The 3DS memory card uses FAT16 format and has a theoretical limit of 32GB. It is possible to get it to accept a card with a higher capacity, but this can have unforeseen issues.
The 3DS transfer tool allows you to transfer DSI games from a DSi to a 3DS.
The Nintendo DSi supports SD and SDHC Memory cards, and it should also support MMC, but I'm not 100% sure.
No the Nintendo DS does not have a memory card. The game cartridges contain the saved file information on them. Therefore, you cannot play your file of a game on somebody else's game cartridge.
R4i 3ds card is just a flash card, the 8GB memory card is just an additional choice, that is, you have to pay extra money for the 8GB memory card. R4i 3ds gold has been in market for a long time and enjoy a very popular reputaion, while r4i gold plus comes out this year and lots of people never heard of it .
No, the 3DS will not read roms that are placed on the SD card. It will not read any unregistered game data from the eShop either if it was not bought on that specific 3DS (except for system transfer)
