Nope, the formes did not exist yet, even if you trade from platinum, it will appear in its regular forme, losing the signature move of the platinum forme.
no not at all
you can't catch any other forms of rotoms other than the normal one on diamond and pearl, only in platinum.
You need a rotom then you can get to the next floor where you can change rotoms form and to get rotom you have to trade from diamond pearl platinum
yes you should try going on to codejunkies.com to find it
You must have a rotom from Pokemon diamond/pearl/platinum and have it as the first Pokemon in you party. Then take it to the lift and rotom will let you use the lift. After the lift has stoped you should be able to change rotoms form
you can't you can only change it in platinum
1 unless you breed
yes it will change the time in Pokemon in either Pokemon diamond and pearl.
You can't. It has to be Platinum. If you get Platinum, you need the Secret Key. You can't get that anymore unless you have an Action Replay.
I'm sorry but its impossible
trade diamond from Pokemon diamond onto Pokemon pearl
You trade Magmar from Pokemon pearl,diamond,or platinum to ether Pokemon pearl,diamond,or platinum.
