I watched this run and while was checking this run, I stumbled with more improvements (I haven't calculated exactly how much frames I saved on these rooms): - earlier menuing on the pebbles path - slingshot path - giant enemy (the most difficulty path to optimize) - earlier exit on the shield path - castle entrance (probably is also present on the first published run of this game, i think) - earlier end input Also, I noted that after the end input, this run and the published run ends with this screen (you need to wait approximately 143 frames after the last input). But if you press a button on this screen, an another screen appears (also present on the first published run of this game, although another button was pressed to finish this screen). After this extra screen, the game restarts. I don't know if the extra screen can be a good choice, but I decided to post both movie files (total improvement - 63 frames): with extra screen - Header changed (but longer input) without extra screen (but still end input earlier) - Header unchanged Since I'm not familiar with this game (I only played a bit, sometime ago), I don't know if there are more paths to improve (or probably will loss with a later desync). EDIT: Someone voted no, but it wasn't me. :p
