Pokemon Platinum Action Replay Code Cheat for 100 People Met and 100 Flags in Underground. Here's the code 94000130 FCFF0000 B2101D40 00000000 00003CC8 00000064 00003CFC 00000064 D2000000 00000000 Type that in mate. Then press L+R, and maybe select, I did all 3. But if you check your card after you'll have the extra star and VOLA! Your set.
