OK, so I am doing a project on DOS in my high ability class at school. I'm specifically using MS-DOS, which is why I have stayed away from DOSBox, because when I looked at it, it didn't look like ms-dos at all, which is what my project is about. I don't know what computer this will be running on, as the schools tech department is trying to create an administer account on it, although I believe it will be a Dell Optiplex. If anybody wants to know what the specs are, I can tell you when the computer is ready. But anyways, alongside just showing a working version of DOS, I would like to put a game on it, Oregon Trail. I have heard DOS has issues in VirtualBox when it comes to games, but I really need to know how I can do this. Thanks
