You need to DLDI patch the .nds file with the correct module for your type of flash card (GBAMP, Supercard, etc). 
If using the FAT version, the "data" folder must be placed in the root directory of your flash card filesystem, while the .nds file can be run from anywhere.
If using the EFS version, you don't need to put the "data" folder on your flash card, but if you have problems with EFS not loading, put the .nds file in the root directory of your flash card filesystem.
