>>37153009I ended up looking into it myself - the javascript for the generator was easy enough. Turns out it doesn't handle secondary targets correctly, which happen to be used for this type of mission. It also generates a random flavor text via the number code instead of a proper one, so the resulting mission looks weird, even if it works.
I did finally run into an example in the game itself, after which pulling the flavor text from the NDS string files was trivial. Mission successful!
