YOU can try other things later, but this is the most simple way for now. You should have neogamma as a channel so you won't need the sd card. search and download wbfs manager and use it to format the flash drive to the wbfs file system. You should be able to put your iso file on it and it will become smaller depending on the game. Plug it into the top usb port and launch neo gamma. In the neo gamma menu change the load games from dvd to usb.
