Yup.. Works fine on my XPS m1730 with Vista Home Premium and SP1.. But, my main emu machine is XP as a few emu's don't play nice with Vista quite yet.. That and I find XP is a tad quicker than Vista and with SP3,, they say its even faster than XP with SP2. lol.. If I don't see a big improvement tho, I will be using Vista on my emu machine as soon as those broken emus (2 of them) are updated. I figured it was just a matter of copying the complete folder, but wanted to make sure.. Thanks fer the info.
