I tried but they don't work. Maybe I do something wrong:
I tried to use the code to encounter Bulbasaur. I activated these four codes:
-Mastercode (from basic codes v1)
-Encounter Main Code (from Encounter codes v1)
-"you need this on" code (from Encounter codes v1)
-Bulbasaur (from Encounter codes v1)
So after I activate these four codes i go on the grass, but I find a Rattata. Is it all right or do I something wrong?
