Gaming Folder structure for irShell USBHostFS Redirect?

[MarcusRaven]

Okay, I know how to stream ISOs using USBHostFS now, but this redirect feature interests me. I know it lets my PSP think the computer is my memory stick, but how would I get my games to show up? Is there a certain file or folder structure? I can't seem to figure it out. There is something I'm testing that needs this specific feature, so any help is greatly appreciated.
