Fast forward on your ds I think 21 days. Your two hamsters should be old enough to breed
now.
Put them both in one cage.
On the bottom screen, at the top, there will be 3 buttons. Press the 2nd button that has
2 hamsters and a heart in between them. Select the 'yes' button when it asks if you want
then to be partners. Now, they can breed.
in your cage, put as many water bottles AND food bowls as you can fit, but still have room
for the hamsters to move around. Fill them up or the hamsters will get sick and not
breed.
Keep them together all night long with it charging and the top of the ds opened. If it is
closed, it will pause the game and not work.
In the morning, go to the store and talk with the manager. He will say that your girl
hamster is pregnant. If not, then keep then together longer.
Now that she's pregnant, SAVE and turn it off. On the main page of the ds, fast forward
10 days.
Go back to your game and check on your girl hamster. You will see a baby!
It will say the color and gender of your hamster. If you don't like it, turn off with out
doing anything and go to it again. Keep turning it off and on until you get the hamster
you like.
Note: If the hamsters that are mating are the same color, the baby is probably going to
be that color. Don't waste your time trying to get a different one. If they are two
different, solid colors, them the baby will be one of two.

but i have two diffrent colored hamsters parnerted and the baby came out to be just like
the mother not diffrent

Don't the hamster's have to get along before they mate? Or at least spend lots of time
together?
