I think it's trying to put it on the SD card and when I go to paths, I don't see how to change it to USB.
you cannot use a wbfs formatted USB HDD to put on GC isos
Sorry... just could not resist
But, there is your answer as to why though.
Perhaps the best options for you would be to either:
1. abandon WBFS and use FAT32 (this is the best option, and what most people use nowadays, it would definitely allow both WIi and GC titles on same HDD)
or
2. split the HDD into 2 partitions, one WBFS, one FAT32 (but not sure if this option would work, or if the WBFS partition can be "shrunken down" without being damaged)
I recommend option 1, just abandon WBFS, it is well outdated anyway.
Also, while I am here... may I please report a small game compatibility problem, and request a feature? (not sure how many people would use it though)
First, the bug. USB Loader GX has problems with Korean isos, due to them using a different comon key from normal. Support was added in d2x cIOS and CFG USB Loader a while ago though, so the cIOS does support them and they CAN be launched...
However, whenever USB Loader GX tries to access anything on a Korean disc (such any file, like banner info), the app crashes with a code dump. I posted a fix for this in this thread a while ago, but it appears to have been overlooked. Here is the original post containing the fix:

Also, here is my request. Would it be possible to add support for the titles.txt? (Just like what CFG USB Loader has)
I mainly use it over the gametdb titles for custom naming my .iso with my own naming convention, and for manipulating the order in which they appear in the list during display and selection.
...Or is there something exactly like this already implemented in USL Loader GX that I may have overlooked?
@Cyan what do you think of these two things?
I appreciate what you guys have done with USB Loader GX thus far though, and I know these two things may not seem important, but it would be great if they could be added whenever you get the time.
