Introduction

This movie obsoletes 3542M (TASVideos). There, Alyosha discovered that delaying the start by 2 frames, you get dealt a better hand on the first stages. But he also mentions that probably an exhaustive bot-based method might find a better solution for the overall game. Here it is.

⸤⸤⸤⸤((⸤⸤This is my anticipated April's fools submission. It's a serious movie tho. Where's the joke? I spent around 50 hours adapting the Stella emulator to run with my bot. Atari 2600 emulation is extremely complicated due to the interaction between the different chips, especially the TIA. I am so tired of this, I wanna go back to NES.⸥⸥))⸥⸥⸥⸥
