Wow - it reminds me of a graphics problem I had when making a Paper Mario TAS: If you are at frame B and load frame A, the graphics output will be first A, then B, then A+2, ..., instead of A, A+1, A+2, ... . The problem is that the frame B will get into the final movie. This happens when I was using Bizhawk, replaying without doing anything else. It also got into Kage's video, too. For example, when in Chapter 8 Mario is about to open the door that leads to the Bowser #1 fight, the screen turned black for a short time, maybe due to a loadstate.
I don't know why, but I don't think this should happen. (Super Mario 64 doesn't have this problem.) Is it because Paper Mario maintains two frames simultaneously?
By the way, Kage and Malleoz, thank you for making Any% TASes of my favorite game!
EDIT: Malleoz's movie replayed on Twitch has this problem too, for example, when Mario obtains the Goomnut before leaving Goomba Village (Twitch time 27:21)
