WinUAE v2.7.1 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 v2.7.1 Beta 4 changelog:

- More than one horizontal DDFSTRT-DDFSTOP window is now accurately emulated without requiring any hacks. Random garbage between display windows is also gone. (Subtle Shades / Nuance) - Removed some more obsolete variables from display emulation. - Saigon Megademo fix got accidentally broken in b2. - 260b17 "strange right edge overscan display shift" optional hack removed, new delay/shift register behavior creates identical output automatically simply by reseting delay counter (hpos counter) at the end of scanline. NOTE: Some programs with large overscan can now have small graphics corruption in right border (gap in graphics), it is not a bug, it is accurate emulation. (For example Back in Bizness / 2000AD) - Some OCS only programs may now have graphics corruption in ECS mode (if bitplane DMA crosses scanlines), this is also not a bug, real hardware would show even worse corruption. Someday this will be more accurately emulated. - Agnus vpos counter increase delayed by 1 cycle. Fixes Hit the Road / Flash Production "Floffy2" part. - Keyboard leds as power/floppy/etc indicators are now properly restored back to original state when keyboard input is not active, changing led config on the fly also works now. - Exiting GUI with close button or ALT-F4 didn't save GUI position.
