How many frames per second does the NES use? I don't mean the actual "physical" frames per second displayed by a TV screen and I also don't mean the refresh rate of an emulator window. I mean the following: When I use FCE Ultra 0.98.15, I can stop the game. And then, with the press of a key, I can advance the game frame by frame. Now, when the game runs in normal time, how many of these frames equal one second?
