"Something" broken sound?! ... It seems working fine in WinUAE 2.0.1 (2009-12-23)!

They attempt to create NTSC mode by writing to Agnus scanline count register (VPOSW) but it is done using method that makes no sense. I have no idea why it is done that way (and I am even sure how it can work..)

Old versions didn't support this kind of refresh rate programming (used mainly in games, Dynablaster, Soccer Kid and Wings of Death)

EDIT: added hack that prevents moving vpos backwards. It wouldn't have worked correctly anyway because display scanline and Agnus scanline are glued together in emulation. It would require major changes to support vpos tricks fully and it really isn't worth the trouble in near future.
