@Kale: when you added interlace mode, svn 5389, you broke the SNES Test Cart (check end of Mode 0 demo, at the beginning: the stars should become smaller, while now it is the rest of the screen to be squeezed)
could you take a look? I don't know if interlace should only affect hires modes or all Modes 0 -> 7 but this way it is broken...
