Help, Magic 3 Problem!!

[Ultimadragon]

I just got a Magic 3 installed in a v5 console, (the guy ran out of Messiah 2 and said the chips were practically identical). Although everything boots fine, i find that the ntsc ps games seem to play up a bit. I have checked the forum but i don't think think its the same problem other people have. The colors are fine, but its just that the screen seems to have been shifted up a couple of inchs.

THanks FOr your help in advance
