My book "Porting Video Games to Fast Simulators with Agents" is out! Over the past year, I've been trying all sorts of tricks to reimplement my favorite games in rust, C, and CUDA so I could have more control and even get them so fast that I could train neural nets in them. I've done this for Minecraft 1.11.2 (netherite -- my pinned), New Super Mario Bros Wii, Mario Kart Wii, and Terraria. This guide is aimed at not just documenting the process, but showing a super sped up version of the /goals I ran and the decisions I made at each step, letting you stumble into the same questions to learn my style properly. I aim to iterate on this like I do with all my projects, so I'm super pumped for any feedback you have. I included a ton of visuals and poured my heart into making this a fun and smooth read. Hope you enjoy!
