Sounds very cool. The menuing in DoaE is probably one of the game’s rough edges for some folks coming in, even if people do eventually figure out how to fly through them.
LLM code generation has been such a mixed bag. I’m honestly a bit surprised you were able to get that much out of it for ROM editing, given there are some real novel aspects involved in what you described.
I find it can work wonders when you tell it specifically what to do and how to do it, or tell it some specific details about what to fix or how something should be changed. But “vibe coding” as folks call it—seems really rough around the edges to me. It’s been great for making some one-off non-production tools, though.
