Make sure your DS is in Manual Mode. When you turn on your DS, instead of going into the game tap a small button at the bottom of the screen with your stylus. Then tap the clock. Next tap the buttonon the right. It will come up with the current time. Use the arrows to change it.
You can't. Go to the settings on your DS home page and the time on that will be in diamond, pearl, heartgold & soulsilver. Welcome:)!
Pokemon Diamond and Pearl both have set of Pokemon that they catch. For example Diamond gets stunkey and pearl gets glameow.
The day of the week in Pokemon diamond and pearl, is the same as your handhelds time and date i.e. if it's a Tuesday on your system, it's Tuesday on Pokemon
You can't really "replace" a pokemon. You can set it free to the wild, though, by pressing "release".
I do not believe there is, but i MIGHT be wrong. Sorry :(
you don't it is only avalible in pearl, diamond, and platinum.
People on GameFAQs might be able to help. http://www.gamefaqs.com/boards/2000360-pokemon-diamond-pearl-platinum-trading
No because...... When you first set your wii to pkmn diamond or pearl, you have to set it to only one. If you want it like that, you have to transfer it to pear and trade it to diamond. The answer to your question is NO. -KANEster
mount moon isn't in Pokemon diamond. it would be in FR and LGMount moon is located in Kanto, not Sinnoh where Diamond is set. You may be thinking of Mt. Coronet which is accessible from Orebrough or Hearthome city.
You can't. Sinnoh is only available in Pokemon Diamond, Pearl and Platinum versions which are set in sinnoh.
The entirety of Pokemon Pearl and Diamond is set in the Sinnoh region. There is no way to revisit any of the other Pokemon world regions.
you would have to set loose some Pokemon in order to make room for other Pokemon.
