Ok mate, i will test it too and after i played it in the next time with an other console i will tell you...
the really screw thing is that Iggi played NTSC and it was normal, then he played the pal and he was much faster (you can see it at the begining too, its like a jump into the front and then he rush away...) and after backl to NTSC it wa snormal again...
so, we will see! If i have an answer, we will show you the difference... so you have all types of harwdare at home?
