Okay, cool. I tested it out, and I do like the flow, but at the same time if I tap a direction instead of holding it, it'd be nice if it automatically moved to the next cover. I had the issue with only a certain number of covers being loaded as expected too, no big deal there (though the disc images load no matter what, maybe that's what you meant in the first post). One other thing is it'd be nice if you could use up and down for faster scrolling, or if maybe the longer you hold down left or right, maybe it speeds up after a while.
And then the last thing, I know that on the iPhone with the touchscreen, you swipe right to go to the left, but I'm not entirely sure that makes sense when using the dpad.
Great work so far though.
Edit: Also, if you get a code dump on load, make sure that you've turned your USB drive on first.
And also, I like how everything is filling up my widescreen display without a separate version and without separate images, everything still appears to be the correct aspect ratio, mostly.
The center image looks slightly too narrow though (looks to be that way in your video too), but that's not a big deal either.
