SNEmulDS help

I'm having trouble setting up roms for the SNES on my M3 Real, and I'm not sure what I'm doing wrong. I put the snemul.cfg into my System folder (is that the root?), the SNES games folder with an Earthbound rom from coolroms.com and SNEmulDS.nds in my system folder as well. When I start the SnemulDS from the Mycard thing,and hit roms, no roms come up. Please help.

no, the root is the highest level, so after you double click the drive letter in my computer, what you see is the root.

Thanks! It worked.
