First off, not to be mean (well kind of to be mean) the map will definitely not be played. It'll probably look horrible, even if you did just decompile it, I'm sure you will mess it up beyond any playable state in a matter of minutes. You're new to mapping, and you should learn how to map before you do anything you want to post on here. It'll be ripped apart and you'll end up getting pissed at us because we think you suck.
With that being said, make your own maps, but don't release one until you finally learn how to light, and add entities. No one here wants to see your horrible looking maps, especially if they are unlit.
