I know what he's asking, and I already have an answer for you. The answer is no, you cannot parse a scenario file to load like Sapien does. You are asking to hook the game engine's functions into your own application [which I know you can't program because nobody here that I know of can hook it properly] and there's no real point.

Or are you asking just to figure out what is inside those little Scenario files. If so, I don't have an answer for you because I haven't messed with them.
