Steps:
1. Save your game in an area where you can catch a wild pokemon through sweet scent or honey (victory road works good)
2. On the main menu of RNG Reporter, go to "5th gen tools" and select "Find parameters"
3. Input your MAC Address, game version, and leave the buttons blank.
4. Enter the month, year, and the time with seconds
5. Set your DS date and time to match the time you put in RNG Reporter, hit your time to the exact second and wait until the screen with the Nintendo logo appears and goes away.
6. Enter the game with the C-Gear off, use the honey or sweet scent, catch the pokemon and save your game.
7. Start the game with your AR, check the IVs of the caught pokemon and enter in the IVs.
8. Save the results and use them for your seeds.
