WinUAE v4.9.1 Beta 8 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 8 changelog:
- Sprite collision bitplane end position calculation was not updated to 4.9.0+ chipset emulation. Probably didn't cause problems because it was too large and it most likely could not cause any spurious collisions.
- b6 ECS Denise CSYNC fix broke vertical blanking when EXTBLANKEN=1. Made only visible difference if mode was weird (not WB monitor driver)
- If programmed mode HSYNC start is later than normal, use it instead of standard VGA-like config. (More correct horizontal position if weird mode)
- Yet another Copper comparator update. WAIT and SKIP timing change again, all my statefile tests still work (and one that didn't also works now). SKIP comparison check timing is not same as WAIT, SKIP seems to check comparison result just before next copper instruction gets loaded (SKIP comparison active as long as IR1 and IR2 bits 0 are set)
- b4 bitplane number update fix, if number of bitplane was increased after hsync start but before hsync end, sometimes bitplane count change was ignored until next line.
- "Default" filter mode now also auto-adjusts if horizontal size does not match vertical (for example if horizontal is hires but vertical is nondoubled: double vertical automatically using filter scaling). Other modes are not yet updated because it can break existing configs.
- Reverted 490b25 68030+ MMU "CE" mode cycle count update that made it too slow compared to matching non-MMU mode.
