Boot in PAL mode via early startup?
Yes, I did that, my Workbench then can be set to Hi Res PAL and I can verify that by switching to Composite video (the video is in BW, so I know it's PAL)
BUT, when I start the game it changes the screen to NTSC (the composite video is in color now) and I can't see the bottom.
I did try to adjust the OVERSCAN preferences by shifting the screen UP, but the game is not using it and shifts the screen down anyway.
