I have one PC I keep just because I managed to get it to work right on that one and can't be bothered trying to make it work on my newer PC's!! Seriously, it can be fiddly to get working, but does give a great impression of the feel and theme/sounds of a game. When I first started collecting I would try every game I could when I saw something on Ebay I hadn't played in years - if it was one I remembered, pinmame would bring the memories back.
