Yes, the Master had used up all his regenerations and descended into a rotting, skeletal state. However, he used the power of the Keeper of Traken to kickstart the whole process again, taking the form of Tremas (as played by Anthony Ainley). Not sure where Eric Roberts' version fits into the continuity, but then most of what happened in the TV movie can be happily ignored.
