I do have a NTSC machine and i tried using the NTSC tooltype it fixed some games but others the game screen is offset like its too far down and there is a inch gap at the top and the bottom inch you cant see
Thats what happens if you run a PAL game on a NTSC machine. Try running adding the PAL screen modes to your devs/monitors and pick the one closest to your NTSC one. It should display normal after that.
