how do you load a nds rom to play on no$gba

i download pokemon pearl and naruto and than drag the file out into a folder and then wen i try to LOAD IT It says data can not be read please reset

Try extracting the files first.

If you are talking about when a screen comes up and says, "Data could not be read. Please reset the DS game card", then you have to change the save type. Go to OPTIONS> Emulation Options> NDS Cartridge Backup Media.
