I have to thank the mods for letting this post stay open for one because in the past I couldn't get any answers about the differences... and 2nd now I understand why the Advance is not well liked. I have a HDloader and like it very much. It's sooooo easy to use and and the load times are great. A few games don't work with it but so what. I do need a bigger harddrive though. Hats off to you all....
