Long time Ars reader, looking forward to your article (and have a few DOS games to reverse in mind already)!

Is this with a Ghidra MCP or some other technique? And why two models - did you try using Qwen3.6-35B-A3B for everything? (Or 27B or a bigger model since you have the RAM for it)

I haven't paired it with Ghidra MCP; because the games are relatively tiny (I'm starting with one of my personal favorites, Karl Buiter's Sentinel Worlds I: Future Magic, which is like <700KB all in), I made a first baseline pass with Fable a couple of days ago while it was still working and it created a bunch of tiny python tools with Capstone. Qwen picked those right up and has had equal success with them. I might try adding Ghidra into the mix, but it seems overkill at the moment.

I went with a pair of models primarily just to see if I could make it work. It's been fine, but I'm going to rip out the smaller coder model today and try it with just the bigger thinking Qwen model wearing both planner & coder hats in the same loop, just with only the bigger model running.

I'm learning a lot, and primarily what I'm learning is that I'm not a developer and this stuff gets real complex real fast, especially in chasing down all the details needed to make sure I'm taking advantage of the spark hardware!
