Screen 7 has always bugged me. After days of thinking about these mechanics, I realized something that I hadn't thought about before. This idea actually cut time and prompted me to try it out on all the levels. Here is an updated movie file that is 67 frames faster over the submitted version.
#638053819203552517 - Updated Yathzee Inputs for new Disk image.
In my search to regain the 7 frames that I lost, due to a frame rule...I discovered how to exploit the collision detection and turn around maneuvers.
Instead of figuring out the mysterious 7 frames lost, I found 30 more from various places across the entire TAS.
Because there was a 7 frame loss, after one stage, I had to go back and see if I could figure it out how to get that 7 frames back. Unfortunately, it appears that this TAS can't cut enough to change this situation, which could be a frame rule.
