Hey, I was just messing around on ninjahax and I took a .cia file, went into its properties, changed it to a .3dsx file, and then put it on the Sd card. I opened up ninjahax and it showed up! But when I clicked on it, it just crashed the exploit and restarted the 3ds. I don't know much about hacking so that's as far as I got. You real hackers see what you can do with this. I did this with the BigblueMenu .cia file if that means anything.
