Roms in RAR format

All the roms for DS that I downloaded are in RAR format.
Am I suppose to convert them to NDS to play on R4?(How?)
Or does it just automatically load when I drag and drop and play it?

All the roms you dl are in rar format you will need a program to extract it such as winrar from www.rarlabs.com and inside will be a file *name.nds* and there is a tutorial by in the tutorial section i wrote for this on the r4ds and how to set it up =D
