The submission notes state: "this is my first actual TAS using frame advance"
It's awesome that you are using a new TASing tool that you haven't with your prior TASing. I'd strongly encourage you to investigate the
TAStudio tool. It makes visualizing/setting inputs on a frame-by-frame basis for any frame in your TAS. In my opinion, it makes TASing a bit easier as backing up and re-doing portions of a run can be performed while maintining future inputs (that may or may not need changed depending on the game).
Also, make sure your submitted runs are meeting our
rules; specifically in this instance (as Spike mentioned), making sure that the submission gets to the point where the game starts to loop. The
guidelines would also be a good resource to read through.
Keep working at your skills, and you'll (hopefully soon) produce something publishable!
