Hi I was going to sell some of my actual game carts but the games do not provide a way to delete the saves. Now this save corruption thingy comes in handy, which has an effect of triggering the actual game carts to reset the save data and gives you a brand new game cart ready for selling.
Here are the steps: (not minimum, but enough)
1. Play the actual game cart once and save
2. Exit to Home
3. Go System Settings->Other Settings->Profile->Hold L then Nintendo DS Profile to open up GW menu
4. While the actual game cart is still put in, start diagnostic test, you should see 3 FAILs and one OK!
5. Power off and power back on the console
6. Start the game cart, you should see some screens or creating save messages as if you have just bought the game new
7. Check the saves are all gone, profit!
I have done this to couple of games I am going to sell, play, clear, play, clear, none have any problem so far. Just to share
