Basically you plug in your DS, start the flashme program, unscrew the battery cover, and use a metal object short the SL-1 contact to enable writing to a write-protected portion of the firmware. This is where the emergency recovery code is stored. Once the flashing process is done, you turn off your DS. Now you don't need the Superkey, and you also got rid of the health screen.

I find it useful, but there's always the chance that the DS will turn off in the middle of the flashing process (usually happens only on DS Lites though). If you've gotten about 3% of the firmware written by that point, you can use the emergency recovery feature. I personally had no issues whatsoever, but you should be aware of the risks.

If you decide to flash your firmware, be sure to look up more detailed instructions on the Internet. I just gave you a brief summary. There are also some video tutorials on Youtube.

Ok.... Am gonna keep to using a superkey! XD
Sounds safer!
