If you still have a problem, you can read these 3DS related questions to solve your problem.
What happens if you put a 3DS game in a DS?
The DS and 3DS use different processors for logic and graphics. Meaning the 3DS cartridges would have to be "re-coded" (recompiled) into DS code. Good question, but the simple answer is you cannot. The code stored in the cartridge is unreadable by a DS.
Why does my 3DS keep saying the SD card was removed?
it's possible your SD card is dying. Back it up and try a different card to see if the message still pops up. If so, it might be your 3DS and you'll need to get it repaired.

The Nintendo 3DS, Nintendo 3DS XL, and Nintendo 2DS systems are compatible with SD cards up to 2 GB in size, and SDHC cards of 4 GB and larger up to 32 GB in size. All other SD Card types are not considered compatible. miniSD and microSD cards are compatible with the use of an SD card adapter.
