That looks SO GORGEOUS.As a quick way to have game box covers instead of game cartridges, extract this zip file into images directory, replacing original images, and run install.bat again: http://no-info.no-ip.info/3ds/box-images.rar

Too bad I don't pirate 3DS games. Time to start, maybe?
3dsx is a format designed for homebrew. It's a modified ARM executable so I don't really know how you would identify that (I don't think it even has room for a title id or product code. Looks like it's just an executable. But the homebrew launcher seems to display some description of the file... so I have no idea).

3dsx is just an executable, a separate .SMDH file is used for the metadata.
