What game is it? There are only about 2 maybe 3 games that are DL. Super Smash Bros is one, and I can't remember the rest. (Some one feel free to swoop in here with the others.) I would update your usbloader GX and give it another go. Or try another loader like wiiflow. Even the old usbloader v1.5 can rip to usb. I used that for a very long time.
