I've made a website which lets you view your Pokemon stats online. It can be useful if you do trades, giveaways or egg checking. It doesn't allow you to modify your Pokemon.
Instructions Download the homebrew and then add it to your 3DS Go to http://www.boxviewer.xyz Open Box Dumper on your 3DS and select your Pokemon game and wait for it to complete. Your Pokemon should now be visible on the website. I've had to remove the OT because Korean/Japanese characters break it.
