Without any shadow of a doubt, WinUAE is THE most impressive emulator of any platform that I have ever seen, and it has advanced by leaps and bounds from the first versions I ever used (before Toni became "The Man"). I've got to tip my hat to him for both the quality he has brought to the project, and for his dedication to the effort over the years.
While I've been pretty inactive in my own fiddling with emulators for the past few years, I was once a fairly active member of the small army of beta testers that Toni invited to help uncover issues with the beta versions, and I always appreciated the level of attention he paid to any bug reports, as well as his patience in dealing with with incomplete information, and with suggestions that we occasionally offered.
Thanks for all your hard work on WinUAE, Toni! You've set a standard by which all other emulators should be judged, and that is no small accomplishment.
