Roms won't load in NesDS on r4ds sdhc

I cannot seem to load any roms. When I get to the list of, legal recently made, Roms if I select any of them it either brings me back to the File menu or the screen turns black. In the case of the screen turning black if I touch the screen I see that I am really back at the File menu.

Are your roms in a folder named NES on the root of your card?

It seems to be an issue with SDHC. Do you have any non-SDHC cards to test with?

Weird... Mine works perfectly... Did you try like other ROMs for NES? Still, lameboy don't work on mine...
