well, I have seen no regressions in any game I tested (and I think it's because the code checks the real hpos/vpos rather than the latched ones): the games which are currently broken were broken in 0.135-0.136-0.137 as well

those handlers can be made optional though, by always entering in the disabled display case (which directly reads/writes vram/oam/cgram), if any bad side-effect surfaces
