Sadly, I can't look at these right now... My school's ISP seems to block filedropper. I'll make sure to check these out once I get home, though.
Is it possible to download the MPO files to the SD card using the computer instead of using the 3DS browser?
EDIT: I got home now, but I have no idea about how to download things from that website. There doesn't seem to be a download button.
