WinUAE v1.6.1 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 v1.6.1 Beta 4 changelog:
- mixed disk swapper panel id and number of input panel columns..
- magic mouse was unreliable in directinput mouse mode ("mouse *")
- magic mouse can be switched on/off on the fly
- utf8 configuration entries didn't work correctly and caused duplicate entries. (fix by loading and saving config again)
- added generic disk icon image (from Cloanto) that is associated with disk image extensions (if enabled in associations panel) This may change before 1.6.1 if my brother feels less lazy next week
- App Paths winuae.exe reg key created if winuae is run as admin at least once, this fixes some file association issues (wrong or missing icon for example), also some other association updates
- statefile harddisk restore problem fixed (still not guaranteed to work..)
- 60Hz on PAL (or 50Hz on NTSC) sound sync/vsync calculation was incorrect
- in AGA only HAM6 or HAM8 supported. HAM mode bit set with 5 or 7 planes seems to be ignored (OCS/ECS has "HAM5")
- HAM ignored AGA BPLAM (BPLCON4) bits
