Summary	05342: majtitl2, skingame, majtitl2j, skingame2: Hangs at title screen if flip screen is enabled
Description	If the flip screen dip is ON then Major Title 2 and clones hangs at the title screen animation, just before Irem copyright and the crowd sample plays. Prime suspect is the different raster effect irq line number.

No.09930 Kale Developer Oct 28, 2013, 18:20	If you check carefully, title screen transition in Major Title 2 opens up wrongly when flip is enabled. i.e. from edge to center instead of center to edge. imho this one is all about: A) find where the flip screen bit is actually tied. B) fix the raster line offset accordingly.
