WinUAE v4.9.0 Beta 42

WinUAE v4.9.0 Beta 42 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 42 changelog:
- Switching from D3D11 fullscreen mode to windowed mode using GUI caused windowed mode to keep-reinitializing continuously. (CTRL+F12 switch worked normally)
- Fixed wrong condition in check if Denise side BPLCON0 parameters needs updating, broke for example HAM enable/disable until next line (b41)
- Blitter line mode with C disabled also disables C-channel pointer modulo add operations. b39 update was not complete. (Methylate / Focus Design).
- Interlace mode last 2 lines (if Overscan+ or Extreme) had swapped long/short line (last line/line zero "wrap around" point), LOF toggles at this point but display device does not see it until few lines later.
- Fixed buffer overflow that caused unexpected crash due to internal variables getting corrupted. It happened if mode was RTG (native chipset not active) and native mode had copper list that writes to custom registers that can affect colors or blanking, state change was unnecessarily recorded to a buffer that is not in use if RTG mode and after long time (can be 100 minutes or more), it finally overflowed. Recent blanking updates introduced this.
- Programmed blanking change was not always fully detected, leaving partially blanked border in some situations.
- Enabled Remove interlace arfifact option without interlace mode: bitplane overrun emulation was not possible.
- Remove interlace artifact option last line flickering/garbage is really gone now. (Blanks extra line(s), this is not really the correct way but too late to fix it properly)
- Bitplane pointer pointing to upper 512k chip ram in ECS 0.5M+0.5M config didn't use indirect read routines. (Fixes Cen / Rare ECS 0.5M+0.5M config corrupted vector objects)
