Homebrew Changing the default directory on NesDS mod

[KOman]

So, I downloaded nesds mod and it said something about the default rom directory being set to a folder named "ROMS". Included with the program was a .exe file that can change this directory. When typing in the new one, is it possible to set the directory as on folder or two folders upstream of the folder in which the emu is. What exactly would I type to do so? Also, I currently using the most recent version of nesds which is great except for the fact that once I load a rom, I cannot change it unless I power off the system and turn it back on - whenever I use the touch screen to access the menu and click on the "Load Rom" option after an initial game is already loaded, the program just freezes up. Is there any way around this? Any information would be very helpful. Thanks in advance,
