WinUAE v2.8.1 Beta 2 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 v2.8.1 Beta 2 Changelog:

- Quickstart GUI disk eject button was unreliable. - HAM mode right border in some situations (Uridium 2 title screeen in some filter modes), also restored proper operation (got broken long time ago) of original "fast mode" if HAM scanline does not have any color register changes. - CIA update (which I forgot to mention in b1 changelog) improved, was not fully compatible if CPU was faster than 68000 , do not trigger CIA interrupt while CPU is accessing any CIA register (not 100% confirmed but seems to be true), this also made b1 CPU mode switching unreliable. - Reduced diskready (motor rotating at full speed) activation time by small amount, fixes Critical Mass / Parallax. - Disk inserted (if replacing existing disk) and disk ready bit setting time is now more "random", now delay time counts scanlines, previously it counted vblanks (=disk was always inserted at vblank) - Removed 270b16 Windows 8.1 mouse bug workaround, bug seems to be fixed.
