Emulating and debug tips

Guys,
        which emulating software do you usually use? M$ does have emulator and 
images for WM2003 / WM5 / WM6.
But not linux tools, AFAIK, can use M$ emulator images. Or am I mistaken?
        I'd like to work with tty application (i.e. see, how connect process 
goes on). What other tools, except gdb,
could you recommend?

Thanks
