I forgot I have windows on my mac too, so I just switched into windows and used WinSCP to put the NES emulator on my iphone, then all I had to do was right click (in the winscp browser) on all the files I moved over to the iphone for the NES emulator and go to properties and change the permissions settings to 0777... This was way easier than trying to understand all that chmod stuff everyone is talking about, I dont even know where I would use that command...lol. But now I have my NES emulator working great on my iphone
