Backing Up GC Games

Well I know of the OLD PSO glitch trick, but I was curious if there was a less expensive way of burning GC games. I was thinking the lines of Qoob Pro, you know with it being able to hook up to the computer I was wondering if there was a way to stream the game files via USB port and turn it into an ISO? I think there was a way of BBA and NGCDev ripper? Not sure of how that exacly works would someone mind explaining it to me? Thanks for anyone that can help.
