3939TODO:
40- both games almost likely uses unemulated V9958 YJK mode(s)
41  http://www.msx-plaza.eu/home.php?page=mccm/mccm72/schermen_eng
40- sexyboom hangs at snippet 0x2ca0-0x2ca9, patching 0x2ca7 branch makes it to be fully playable;
41- v9958 screen modes 10/11/12 aren't 100% perfect (wrong pixels in some places);
