Open up act.img in hxd or another hex editor of choice, then look around in it for action node paths.
Rise and Lemon have more or less figured all of the paths out except for just a couple or so and all that they found will be included in the player selector. Sry I missed the planned release date of the player selector but we are still working on it and I am having Rise check over the code I have added to it since we want this to be as bug free as possible.
