Yes, the game is not finished. White can capture T18 with a ko fight in this position. Current Japanese rules force the players fill all dame's before finishing a game. And, as a terinology, we never call S6 dame. A dame must be in a boundary of the territories (ie, never in a terrotory). Just Black has to play S6 (or around) before the game ends, in this case.
