Emulator Problem

When trying to play Harvest moon DS that I got from this website, I use no$gba and it always say's "Could not read the data. Turn off the power and reinsert the Game Card." What should I do?

Try changing the save type around.

how do i change the save type around? :o

Have a look under settings, it's really not that hard to find if you just use your eyes.
I know for a fact the option is there on no$gba.If you're not using no$gba then find something similar.
