WinUAE v4.9.1 Beta 5 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 v4.9.1 Beta 5 changelog:
- Filtered lores had wrong colors if host graphics mode was 16-bit.
- Horizontal DIWSTOP = last possible horizontal position (+1 more would cause always on hdiw) didn't ignore DIWHIGH AGA H0/H1 bits, if either (or both) were set, always on diw was detected.
- Disk not in ADKCON FAST mode and normal 2us MFM disk in drive: disk index was unreliable.
- Some normal programmed WB modes unnecessarily enabled slower cycle-based custom chipset emulation.
- Another HBLANK fix, if previous line ends in border closed state and without hblank start, next line also starts in border closed state. Programmed HBLANK + AGA only, ECS Denise CSYNC blanking always resets border state when HSYNC starts.
- Previous A1000 3 lores pixel earlier change was not accurate, it is OCS Denise feature (including A1000 Denise) and it isn't hblank end difference but for some only bitplane data is not allowed until first 3 pixels, border works normally (Previous test used black border color which hide the 3 lores pixel border stripe). This is now fixed.
- In some situations old bitplane data was not properly cleared when number of planes decreased mid scanline (including change hidden in invisible part of scanline). b4 number of bitplane change side-effect.
- Adjusted overscan+/extreme positioning.
