WinUAE v2.3.1 Beta 9 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 v2.3.1 Beta 9 changelog:
- emulate mouse counter behavior 100% when joystick is connected (increase/decrease counter by 4 when two lowest bits change from 0 to 3 or vice versa) Most likely no program cares.. Mouse cursor movement is now exactly same as on real Amigas when moving joystick in mouse port..
- "Delete Saveimage" button didn't work, broke when CD image GUI was added
- save CPU/chipset ratio to statefile
- attempt to load disk image and harddisk paths in statefiles from current dir, current adf/hardfile paths and directory where statefile was loaded if original path or file is missing
- harddrive statesaves didn't save correctly if more than 1 harddrive was configured
- b3 "stop linedraw if blitter register modified while active" hack didn't always clear blitter active bit
- stopped CPU in CE mode was saved incorrectly to statefile (introduced in some earlier beta)
