So, due to site complications, my original post was not actually posted. Here's my best recreation I watched the first place run, and noticed that the setting for "Limit framerate" in Projest64 was unchecked. To my knowledge, that means the game is running at a higher speed (almost double). The audio is noticeably sped up, as are the animations. Now, I could be very wrong, and it could indeed run at just the same speed, but as far as I can tell it's essentially PJ64's version of turbo

Thank you for bringing this to my attention. After further analysis of the footage, is saw an increase in tetromino speed, and at least one instance where auto-drop is not used, proving there is at least one unfair benefit to the run.

Didn't even know that was a thing. Found the setting, checked the box, and resubmitted. Thanks for the heads up, Charlie! [:
