And AI stands on the shoulders on human labor.

Obviously these static recompilation tools (and I purposefully picked ones where I saw no obvious help from LLMs, though I didn't look too carefully) had massive help from prior emulation projects, but they were/are still novel projects (maybe barring Suyu).

Also, it's very possible that N64Recomp used direct ideas or even code from IDO Static Recomp, since that's a project that recompiles IRIX programs, and there is a direct link there given the SGI lineage of both hardware architectures.

The main point I was trying to make is that AI doesn't need to be used to attain speed when it comes to porting games now that these ideas and tooling exist, as these tools can now be used, or new ones creates for consoles that don't yet have them.
