Thanks loads for the guide! I was stressing over the encounter type like crazy. I even thought that Pokégen somehow messes up my whole box :3 Cuz my Soul Silver had different encounter types (grass, cave, etc)
But I got something to ask... Like when you make a (Pokétransfer) Pokémon..... Should the PID follow the rules of the previous Gen (nature included)? Cuz since it was "transferred" shouldn't it keep the 4th Gen PID?
