Pokemon Soul Silver Cheats

It can be a little difficult getting the last 2 Unowns (! and ?) in the game. Well, I will show you some ways to get them.
1. Complete all 4 Slide Puzzles.
2. Unlock all 4 Doors at the back.
3. Catch all 26 Unown (A-Z).
4. If you drop down the holes in the back rooms, you will see some messages.
----------------------------------------------------------------------------
ONCE YOU DO ALL THAT...
Bring an Unown to the Main Entrance, and click on the yellow tile at the back.
A scientist will come up to you. You will both go back to the Research Lab, and he will add another entry.
----------------------------------------------------------------------------
Once you do all that, go to the Main Entrance and Unown ! and ? will appear. Just run around, and they should appear!
Happy UNOWN-ing!
