Perfect timing - Sharopolis just released a video [0] using this exact disassembly to mod Super Mario-style physics into the game.
He used Claude Code to 'vibe code' the assembly changes, leveraging the fact that the disassembly identifies about 2KB of unused memory. It’s a fascinating look at how LLMs can now navigate and modify 40-year-old Z80 assembly when provided with a well-documented codebase like this one.
The video sparked a lot of discussion in the comments, with some people being very upset he used AI for this.
