What is it that you are trying to do? Find NES roms or put them on the ipod? You don't need a specific program to install them on the ipod, you would use the same program you used to get any other app on the ipod, which is the one I mentioned above. That seems to be the best as I have had no problems with it. You just enter in your IP, then your name and pass and you are in.
Then you look for that location I told you about and you create those two folders and then you drop the roms in that last folder. In order to find VAR you have to be at the root of the ipod, if you aren't at the root, then all you will see are like 1 or 3 folders, if you are at the root, you should see about 6-10 (in which you see var and follow the directory I gave you and create those two folders exactly as stated above). Then once they are uploaded, you just go on your touch and open up the NES Emulator and they should show right up!
