I'll write a blogpost when I actually have it working, but basically I gave the game .msi installer to claude opus 5.5 and said to read these blogs:

  - https://blog.chrislewis.au/using-coding-agents-to-decompile-nintendo-64-games/
  - https://blog.chrislewis.au/the-long-tail-of-llm-assisted-decompilation/

And to setup a harness that will decompile the game and start doing a matching decompilation of every function. It set up a bunch of tooling and started a service in the background to do this actual decompilation campaign. I put some instructions into the main opus chat now and then to e.g. add automatic git pushing including a nice svg chart of progress and to switch model strategies here and there i.e. to do a first pass with a cheap model and then switch to opus/sol if the small model can't solve it.

I could now one-shot a new game, yeah.
