WinUAE v2.7.1 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 v2.7.1 Beta 2 changelog:

- BPLCON1 mid scan line modifications now should match real hardware 100%. This was very big change, old emulation was functionally close enough but very far from real hardware behavior. Old code couldn't emulate some side-effects correctly. - Partial/full scanline based mode ("SPEEDUP") is again used more regularly, "is it safe to use" check got partially broken during 2.7.0 betas. It is also more optimal in AGA 32/64-bit fetch modes. - AGA border sprite in right border and 2x or 4x horizontal sprite pixels (vs bitplane pixels): sprite's rightmost pixel(s) were missing. - Superhires and top or bottom border sprite: graphics garbage was seen in border area, memory corruption was also possible in some situations. - Magic mouse + mousehack mode now always stops keyboard input when mouse is outside of emulation window, even if window still has focus. - 68020/030 CAAR register preserves also all reserved bits. - Disable JIT if config has 68000/010 CPU and non-zero JIT cache size. - 68020 CE broke interrupt state fetch, interrupt didn't clear if write to INTREQ was immediately followed by RTE. (b1) - Does not anymore require SSE2 capable CPU (b1 did)
