Yeah, there's a couple of ways to do it.
You could use 2 seperate cameras then paste each cameras render image to the screen, or even texture it to an object, a plain for instance.
Another way (my preferred way) is to use 2 camera views, so each loop you update a different view, using SET CAMERA VIEW xa,ya,xb,yb
A benefit to using switching camera views is that it doesn't impact frame rate as severely (if at all). I'd be happy to make a small example of switching camera views for you.

Actually, if it's completely 2D, you'll be just fine drawing the map around player 1 on one side of the screen and then the map around player 2 on the other. Otherwise, if you're using 3D objects to make a top down kind of thing, Van B made a good suggestion.

or use SET CAMERA VIEW for two camera, specifying the coordinates for each one on the screen.

Why switch camera views? Make 2 cameras, and give them the 2 different camera views. You get a higher framerate by having 1 camera and switching the view every sync, but then each view is only rendered every other frame.

You could render both views, but if the frame rate is high enough it's negligible. With 2 views as opposed to 2 cameras, you have much less hassle with shaders, and it's easy to switch back to a single view, and it can adapt to the screen resolution much better. Imagine you have a 2 player game, top down with 2 characters - with the 2 views method you can switch back to a single view when the players are close together. Players can quit out and start up without affecting things too much as well.

Extra cameras are best for effects like refraction, IMO it's overkill to use them for split screens.
