Well, I've tested a few different hard drives (each of which are on the wiki as "working"), and a few different games (each of which are on the wiki as "working" - including Mario Kart and Kororinpa), and my conclusion is that the whole USB Loader thing is basically unusable. Random freezes makes it a real PITA to do any serious gaming. I'm sticking with DVD-Rs thanks. Maybe in a few versions time it will be usable, but at the moment it's more trouble than it's worth. Anyone else share these thoughts, or is it just me/my setup?
