Button Controls
You're not going to get very far in the game if you don't know how to use the controls! The directional pad obviously moves your farmer around and navigates up and down through the menus. The rest of the DS' buttons are assigned to other tasks.
A Button
The "pick up" button. You only have to stand facing an item on the ground and
then press the A to pick it up. If you press A again then you will throw it
back on to the ground. You also harvest your crops with this button, and start
conversations with the villagers. You can even talk to your animals!
B Button
Hold down the B button and press the directional controls to make your farmer
run. You can do the same thing to make your horse run faster.
X Button
When you are holding something edible in your hands, you can eat it by
pressing X.
Y Button
What you have in the red-colored Tool slot in your rucksack will be used when
you press the Y button. Hold down Y if your tool has more than 1 level and you
want to power it up. You can also plant crops if you have a bag of seed in
the red slot of your rucksack. If you were holding something (via the A
button), pressing Y will put that item into your rucksack.
Start Button
This will pause your game where ever you are. Unfortunately when you pause
the game you don't have the ability to interact with your lower screen.
There's no way to pause your game to stop time, access items in your
rucksack, and then unpause to continue.
Select Button
It is not used and has no purpose.
Left Shoulder Button
To whistle for your pets you just have to press this button. Sometimes the
pets will come to your call, but most of the time they'll just ignore you
like pets typically do. You can also whistle at the villagers when you see
them, which will cause them to pause for a moment.
Right Shoulder Button
The Right button on it's own doesn't do anything at all. If you combine
this button with one of the face buttons you can rotate between the
different equipped items in your rucksack. It will typically be easier
for you to use the touch pad and the stylus to do these same tasks,
especially if your rucksack has a lot of junk stored in it.
Right + A Button
The items that can be held above your head will be switched. As
you hold Right and press A your character will hold a item above his head,
then switch it with a new item from his rucksack. This rotates the
content of the rucksack's Green slot.
Right + B Button
This will rotate the equipable tools from the rucksack's Red slot.
Right + X Button
Rotating your different accessories into your rucksack's blue Ornament
slot is done with this button combination.
Right + Y Button
This will do the same tool rotation as the Right + B Button command, but
this will reverse the rotation of the tools. If you had rotated
past the tool you wanted with R+B, you can reverse it with R+Y to get the
tool to reappear in your red equipment slot.
