WinUAE v4.9.0 Beta 27

WinUAE v4.9.0 Beta 27 is released. WinUAE is the commodore amiga emulator for Windows. WinUAE is a mostly complete software emulation of the hardware of the Commodore Amiga 500/1000/2000. A Commodore Amiga, for those who don’t know, is a 16/32 bit computer system based on the Motorola 680×0 CPU and a few specially designed custom chips that provide very good graphics and sound capabilities. Its first incarnation, the A1000, appeared in 1985, followed by the highly successful A500 and A2000 models. WinUAE is a port of the originally written for Unixish systems UAE; but over time, it seems the Windows port, WinUAE has become the best version available on any platform. WinUAE is free software: you are welcome to distribute copies of it and/or modify it, under certain conditions. There is no warranty of any kind for UAE. For more details concerning these issues, please read the GNU General Public License, which describes the terms under which WinUAE is distributed.

WinUAE v4.9.0 Beta 27 changelog:
- Graphics glitches fixed (b26 and b25)
- Some programs (for example Wings of Death) that use OCS compatible 60Hz hack didn't have working vblank interrupt. If write to VPOSW jumped to mid last line, vblank start line check was missed.
- Added some optimizations (for example don't create new bitplane allocation table for current scanline if previous line had identical bitplane cycle sequence)
- Added bitplane/audio DMA conflict emulation that can happen in bitplane overrun situations. In this situation no DMA transfer is done (neither BPL or audio).
- Integer scale filters usually forced all scanlines to be fully redrawn, even if content didn't change.
- VPOSW fake 60Hz now uses 60Hz height if refresh rate is >=55Hz and 50Hz height if less than 55Hz. Matches 1081/1084 etc CRT behavior better.
- "Remove interlace artifacts" last line flickering fixed.
