Hoax, have you tried readme/instruction files? Trying DOSbox is probably NOT the best way to start with your Wiz, it's the most complex (and not working great yet) of emulators. Try something a bit easier like PicoDrive with megadrive roms, then when you get that going well, try something more complicated like UAE4All which is a bit more awkward to get set up, but is running MUCH better than DOSbox. You will have to read the instructions that come with these emulators to know where to put your roms and files.
If you are having trouble I'll help you out if you can, but really you should take a bit of time to get used to how things work on the Wiz, and DOSbox probably isn't something you're going to get working on your first second or even third attempt (took me 3 days to figure out windows notepad was making an arse of my startup scripts!).
