I'm a baseball fan, an specifically of Diamond MInd Baseball, which is solely a Windows based program. I bought Iemulator to run it. The installation for Iemulator are a model of what a manual should be. They take you step by step through what would normally be a hair-pulling process and made it a fairly easy. The price is reaosnable, and everything works as it is supposed to. What more can I say, except when I had a question about something the company responded almost immediately.
