WinUAE v2.6.1 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 v2.6.1 Beta 1 changelog:
- KS 1.3 OFS hardfile fix. Apparently 1.3 L:FastFileSystem does not support OFS. Use ROM built-in FS if OFS partition and hardfile FileSys path is empty. (2.6.0)
- Added emulation of unimplemented FPU instruction exceptions. New FPU "Unimplemented emu" option added to GUI: ticked = emulate all instructions (old behavior), Unticked = instructions not emulated, unimplemented instructions generate exceptions: 6888x: S or D variants are not supported (FSADD, FDADD etc..), 68040/060 only. 68040: usual removed instructions and FINT/FINTZ 68060: usual removed instructions, FTRAP, FDBcc and FScc. FINT and FINTZ are back. 68040/060 unimplemented datatype (packed decimal) is still emulated normally because unimplemented datatype exception requires special pre and post FPU-only exceptions. (This is not guaranteed to be perfect, not that easy to test fully)
- Hardware/software reset didn't reset SCSI emulation fully.
- A3000 KS 1.4 scsi driver wasn't fully compatible with SCSI emulation, write command got stuck in never ending loop. Only reads worked. (WD SCSI chip is quite flexible, it allows multiple and very different ways to send and process SCSI commands)
- Non-prefetch CPU mode RESET/JMP (An) combination detection did only check if it was located in chip ram, it didn't check Z2 Fast.
- Input panel Invert option added. Button and key presses become releases and vice versa. Joystick and mouse (if relative) movement is inverted.
- winuaeenforcer aros m68k debug.library segtracker-like support added.
- Added Tf debugger command that lists FileSystem.resource contents.
- Added system memory list dump option to debugger ('Tm')
- Merge >2M chip RAM with original chip ram pool instead of creating new one.
- Bitplane data (usually horizontally repeating) was visible if sprites were visible in border regions. (2.6.0)
- Do not emulate CIA TOD bug if MMU emulation is enabled, workaround for Amix boot hang. (Until real problem is found)
