WinUAE v3.1.0 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 v3.1.0 Beta 4 Changelog:

- HAM-E images updated only every other line in doubled modes. - Graffiti didn't sync correctly if config was not AGA. - Restart button crashed if hardware RTG was enabled. - PCMCIA IDE didn't work anymore (b2) - .pkd file extension inside archive wasn't autodetected. - Disk/CD insert status message file name was shown as "null" if file was inside archive root. - HD and tape SCSI emulation unsupported LUN sense data was overwritten with default ILLEGAL FIELD IN CDB sense data. - CD SCSI emulator didn't check for non-zero LUNs. - Return SCSI-1 HD inquiry data only if A590/A2091. - Show also REQUEST SENSE command and data if scsi emulation logging is enabled. - 68000 prefetch mode DIVS/DIVU timing update didn't work, always returned 4 cycles due to missing parenthesis. - Switching chip ram and/or slow ram size usually crashed after reset if ECS Agnus was selected. - Some very old statefiles had Z2 fast ram with zeroed autoconfig address, added workaround (broke during 2.9 betas) - Added fl or fl and fc break points to debugger. - Z3 space memory mapping was not initialized if only non-RAM/VRAM Z3 expansions are configured. - Clock sync feature update, previously only 50Hz CIA-A TOD rate was fully accurate. - Load CDTV/CD32 state file, load other state file: CDTV/CD32 CD was still mounted. - Yet another bitplane DMA sequencer emulation rewrite and cleanups. Still some bitplane DMA on/off switch edge cases remaining Switch on bitplane DMA near end the scanline: following line starts DMA for one "block" only, next line works normally. This needs more real hardware testing to find exact conditions. - Source cleanup, moved all kinds of device init/free/interrupt check codes to common file from non-related source files. - Added name to UAE Boot ROM DiagArea. (May be visible in some system info/diagnostics software) - HALT status was not cleared when loading new state file.
