I do have the original game (It's actually called Pinball Arcade, which is Pinball Dreams & Dreams 2 combined, PM me if you want Arcade, it runs great on my 486), but I am not sure if DosBox would run it, so I downloaded the Dreams 1 zip (from here), plus this is the first time I'm using DosBox, so I type Dreams.com, nothing happens. I type Pinball, it says "Install.SYS should be in the folder or game doesn't work" (it is in the game folder). Me = Total newbie at DosBox.

Well you got to set up Dosbox first... you can download frontend called Dfend to help you set up easily... and then you run wizard to get profile to run the Pinball game executable
