As the underground man said, I'm a spelunking MASTER! So, I have your answer.
1. If you have a friend that has Platinum, Pearl or Diamond, go underground with them and find their secret base!
*Or if you have two DS's and tow game's, put them in the separate DS systems and steal a flag from your self, lol
2. When you do, go to their PC and when it asks if you want to take their flag, click "yes"
3. Once you have their flag, race back to your secret base and register it in your PC
4. If you want another prize, go back above ground and talk to the underground man, and he'll give you your next prize for getting a flag
