WinUAE v2.8.1 Beta 1 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 1 Changelog:

- Audio DMA CPU wait hack (that tries to prevent missing samples if program has CPU timed audio DMA wait) improved, now compatible with programs that really need delay after DMA switch off (for example switches DMA off, then clears interrupt request, and then finally waits for audio interrupt). - CPU on the fly mode changes were unreliable (2.8.0b15) - Fixed some GUI strings that didn't support translation. - .ccd CD images didn't automatically load from archive if file was not in archive root. - Disk insert after emulation has been started may have internally set disk as write protected even if disk image is write enabled. (broken since GUI "?" button was added) - Added DMA channel support to memwatch points. Add DMA channel name (or more than one) at the end of debugger w command line, for example COP, BLT (or BLTA if you only want A channel reads) and so on.. No parameter = CPU accesses only. - Null filter didn't check display bounds, fixes possible DirectDraw mode crash when display size changes. - Directory filesystem ACTION SET FILE SIZE will now fail if target file size is >= 2G. (Prevents accidental truncation if program does not support large files) - Added directory filesystem MorphOS compatible 64-bit file size packets: ACTION_SEEK64, ACTION_SET_FILE_SIZE64, ACTION_LOCK_RECORD64, ACTION_FREE_RECORD64, ACTION_EXAMINE_OBJECT64, ACTION_EXAMINE_NEXT64, ACTION_EXAMINE_FH64 and ACTION_EXAMINE_ALL ED_SIZE64. (OS4 packets were implemented long time ago) - AGA and reading non-existing or write-only custom registers work differently than on A500, don't use new more A500 compatible method added in 2.8.0 with AGA configurations. (This is far from accurate) - Mouse device autoswitching was unreliable if rawinput was not supported or was disabled. - If Quickstart mode and sound filter is set to A500 or A1200 emulated or always on: automatically match it with selected config. - DMA debugger now shows CPU and DMA 32-bit chip ram accesses, previously data was truncated to 16-bits. 64-bit DMA is stil truncated to 32-bit.
