I have posted my record on game B in the Circus Charlie thread in the NES section. Here's that post. The .fcm I posted there (here) is 31 frames faster than this run. Because of this, I vote no. I also asked in the CC thread if people preferred the game B run over the game A run, but not many seemed to have any opinion. With all that said, I would be extremely interested if you can show any improvements to the published game A run! Regarding which mode is hardest to TAS, level 1 is harder on game A, but level 5 is harder on game B due to the rope trick that has to be pulled off here. Overall, I would say that with all tricks included, the two game modes are about equally hard to TAS. And I've said this before, and I'll say it again, using the in-game timer to compare runs is not a good statistic, because the timer starts counting down depending on a global timer. That means that even if run A has a lower score than run B at the end of a level, run A might still be faster. Use frame counts rather than the in-game timer to compare runs. Pausing the game at certain frames also stops the in-game timer, as shown here.
