I installed and verified this to work with a USB HDD. If finds the HDD and formats it in seconds. I copied my original MadWorld disc to the HDD via the USB Loader v.1.1. It took about 15 minutes. Then I ejected my MadWorld disc and launched the game from HDD. Works flawless.
I am at 3.2U Softmod and do not have a modchip, so I haven't tested a backup ISO disc yet, but I would have to assume it is needed since there isn't a way to have the USB Loader v1.1 launch the BackupLoader Gamma from the HBC.
If there was a way to somehow combine the BackupLoader Gamma, Ocarina, and the USB Loader, I think we'd all be in heaven.
I also want to go on record on saying the cIOS v9 is fantastic and my BackupLaoder Gamma works 1000% better than on v7 or v8. Whereas I had a lot of 349 errors, v9 seems to work nearly every time I load it. I am impressed with the level of programming coming out lately. Keep up the good work!
