I beat Castlevania III tonight for the millionth-or-so time, and streamed it so a dungeon member here could see.
Unfortunately, due to the framerate issues of my capture setup, the game was needlessly harder (the mermen's shadows on the water in stage 6-0B and 9-04 had to get lucky-struck because they were completely invisible while capturing, so I had to save-state and go fully on hope alone).
Beat the game saving Grant but finishing with Sypha.
