WinUAE v6.0.0 Beta 4 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 Changelog:
- Copper DMA is off and vblank strobe: copper loaded new pointer immediately, not when it get first DMA slot.
- ERSY=1 without genlock now really stops horizontal/vertical counters instead of faking it. Old hack removed.
- Reading AGA color register contents (RDRAM=1) read old value from previous scanline due to RGA bus buffering.
- Some ECS Denise modes had garbage visible in left and/or right side and display ended 1 lores pixel too early.
- Advanced chipset default (non-editable) Agnus revision field didn't always include ECS bit flag. Visual bug only. (Very old bug).
- TV Overscan modes work now, including genlock modes.
- Programmed mode screen width and horizontal position updates.
