WinUAE v4.9.0 Beta 41 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 41 changelog:
- Sprite processing was exited early if sprite horizontal start was zero (which is correct normally). But when combined with FMODE SSCAN2-bit, only "original" sprite is invisible but "doubled" sprite is still visible. Fixes Fantastic Dizzy CD32 background glitch.
- Improve Denise/Lisa internal bitplane pipeline logic, previously undocumented combined plane change + bitplane shift changes mid scanline are now working correctly.
- Above behavior also revealed yet another undocumented chipset feature/bug: if ECS Denise or AGA and bitplane plane count is lowered mid scan line and disabled plane's last bit out of bitplane shifter was one: last pixel appears twice. OCS Denise is unaffected. This is emulated only in subpixel mode.
- Clear all internal display emulation buffers at reset, previously some of them was not cleared. (Possibly could have caused temporary on screen garbage when loading statefile on the fly)
