There isn't an HM Move Charge in Platinum.
There is no "HM" mean look.
You can just reteach it since HM are reusable.
People say you can't, but you CAN make HM moves remove. You must go to to the move deleter (don't know anymore which town/city) and then select the HM move he would say that he can't delete that (HM) move!! Then talk again to him and he will forget the HM move!!
"Talk to the move deleter."
the move deleter in canalave city :) =)
Yes there is an HM restriction in palpark. They do this because some of the HMs from the GBA games aren't available in platinum. For example, Dive is no longer an HM move in pokemon, and it used to be in the GBA games.
Use the hm strength.
You have to have the HM Strength which you can find on Iron Island with Riley.
you need hm strength which you can get from bryon after defeating him in canalave city.

You cannot get an HM or TM of Roar of Time; if you get Dialga at the end of Platinum, it will have the move Roar of Time. :)
