I would like to comment that WinUAE has been very stable and very very usable under windows XP..
I just bought a new laptop computer an HP Pavilion ZV5260us which has 512MB RAM a dvd burner and an AMD Athlon 64, 64-bit x86 compatible processor.. It also has a 15.4 HI DEF widescreen 1600x1050 lcd display..
Recently I installed the preview program release of Microsoft Windows XP 64-bit edition.. Anyway after reading this entire post I decided to try out WinUAE (32bit) on the preview release.. I also have direct x installed on it..
Well I have to say three things, it's FASTER than I have ever ever seen.. I had to fool with the CPU flags but in 64 bit mode running a 32 bit app thru WOW it's AMAZINGLY FAST.. Under 32 bit XP I notice the windows redraw even at 1600x1050 resolution.. On XP 64-bit it's not the case anymore at all you cant see redraw or refresh at all. Sound and video work and everything amazingly well..
Although it's not a 32 bit app running it in 64 bit seems to improve the performance greatly. I am going to benchmark in a follow up post..
