Going to try dimoks udpdumpreader to see if I can see what, if any, error and posthat my results...
Ah, never mind, everybody --- turned out it was stupid user error ---> mine. I had downloaded half a dozen games and they all worked fine. I had successfully dumped 8 games but none of the worked even though I got the code/content/meta directories successfully. The stupid user error was that I did not realize I left the /vol folder on my game subdirectories --- DOH!
So, all in all, DDD and Loadiine GX are *excellent* products. The only title I have been unable to dump is my Wii Fit U that is on my NAND...keeps failing on the same content files...
