yes u take 2 of the same Pokemon (a boy and a girl) and take them to the daycare centre in solacean town or trade ditto from leafgreen and fire red and put it wth a Pokemon in the daycare centre because ditto can transform to that Pokemon it is genderless
^^
that didnt have much to do with the quetion but, you do not need to trade a ditto, when you can get it in the game. on route 218 using the pokeradar.
as far as a know you can't make Pokemon like each other, its either they do or they don't basically.
like any other Pokemon game
Pokemon pearl is just like any other Pokemon game : you've got to catch em all
one like all other Pokemon games
Yes you will get an egg. But however if the daycare man says they prefer to play with other pokemon that is when you will not get an egg
you import them
No. Just like in Pokemon Pearl with the Pal Park you can only trade from Pokemon pearl to black, not back
bye maming one get and the other a life.
keep the ones you want to like each other in your party or put them in the day care together
sorry to dissapoint you but no and that also means no with acrion replay and gameshark and any other cheat device
I personally like Emerald better, but Pearl has better graphics.
level 30, just like in any other game
If you mean breed Pokemon eggs, you put 2 Pokemon together from the same egg group into the daycare, and talk to the man outside after a while. If he says something like "They don't like each other" or "They prefer to play with other Pokemon", then they probably won't have an egg. If they say something like "They really like each other" or "They enjoy playing with each other", then they probably will have an egg.
