I can't speak to when Force Unleashed takes place, but Vader has decided to overthrow the Emperor before Return of the Jedi. In Empire Strikes Back, he asks Luke to help him overthrow the Emperor ("Join me, and we'll rule the galaxy as father and son.")
My favorite explanation is the turn happens somewhere between A New Hope and Empire Strikes Back. Vader ends A New Hope wondering who this Force-sensitive Rebel pilot is ("The Force is strong with this one."). Vader begins ESB knowing that Rebel pilot was his son, and he's decided he's going to recruit Luke to his side.
The recent Marvel comics show the moment Vader discovers the Rebel pilot is a kid named Skywalker from Tatooine, and he realizes the Emperor lied to him about his son being dead. And that creates the seed to kill the Emperor.
