hi guys im new here and a big fan of Wipeout ... bla bla

I have a question and i am very thankful to any answer.

I would like to know if there are any technical differences between Wipeout HD for Europe and Wipeout HD for the USA (for example).
Cause there are some games like Tekken5 DR which runs @60fps in the states but in 50fps in Europe. Today in the HD generation those differences seem to be oldschool but till now nobody could gave me an accurate answer.
