So I got a 2011 15" Macbook Pro I'm trying to run the Lost World Arcade on. I'm a newb to command prompts and all that. I downloaded Supermodel, and then the rom for the lost world and put it as a zip in the folder. Downloaded SDL or whatever and put it where it said. So I read to drag and drop the Supermodel folder in terminal, and then type /supermodel romnamehere.zip.

What am I doing wrong? This is a cool learning process, so feel free to call me a noob or whatever.
