No, but you can now climb rockwalls.
No, Pokemon who know HMs cannot be brought over through pal park, and the dive HM is not available in diamond and pearl, so it is not possible.
You can't get dialga on pearl only diamond can so trade with diamond to get one.
i don't think Pokemon diamond has an ending. so is pearl and platinum.
Pokemon D/P means Pokemon Diamond/Pearl, So yeah it is the same.
if you mean can you get Pokemon from pearl and diamond and trade them to ruby so you can get diamond and pearl Pokemon on ruby. then no you can not. but you can migrate ruby Pokemon. you put the Pokemon in ruby that you want to put on diamond or pearl in the PC. save it turn off. then go to diamond and migrate them. must be in ds at the same time. pal park.
No. Dive is an HM in kanto, so you can't use it out of battle. Some Pokemon can learn dive with no Tms or HMs, but you can't use it as a field move.
You can't catch him in Pokemon pearl,you can only catch him in Pokemon diamond ,so,you,ll have to trade it with a friend
Misdreavus cannot be obtained on Pokemon Diamond, so you must trade one from Pokemon Pearl.
Dive is not an HM/TM anymore so it can't learn dive, but you can get it from a different region so if you trade a Pokemon holding that move then take it off them it can learn dive.
Im Not Sure Of That So My Guess Is No Because Pokemon Diamond And Pearl Are Mostly The Same And Remember Its MY GUESS!!!!!! Hope It Helps^_^
My cousin has diamond and have pearl so we showed that there are diffrent story lines hopes this helps
Generation 4. But there's only been one version of Diamond and Pearl so far.
