It's called Power !!! Me. All it does is power off your DS! This is my first homebrew that isn't "Hello World!" To prove I'm not %100 noob I'll make a version that needs you to press A!
Any congrats on my first "useful" homebrew?
The use of the homebrew is if for some reason you can't turn off your DS (and you can turn it on!)
My Power !!! Me is attached! Enjoy!
