The video that skipped to the actual content was neat, but the author saying "they don't know what they're doing" is very evident by the time you get to the end of the video watching them fumble to find architecture-specific MIPS binaries. Good grief.

He's clearly doing a bit where he pretends to be confused and incompetent, and the punchline of the video is that he ends up with a working Windows CE port. He did a bit of soldering on the N64 board in the video so I think he probably does know what he's doing to a certain degree.

That said, LLMs have gotten extremely good at this kind of thing and you'd be shocked what you can do with this kind of low level work.
