I think it's funny how goblin mode this whole hack is. The memory scanner itself was clearly written by an LLM (using python??) and the way this person goes about hacking the game is very non-reverse engineer but instead someone equipped with very capable tools. No shade to the dude to be clear, I think it's sort of incredibly how possible this stuff is now due to LLMs and doesn't require someone to know how to use Ghidra.
AND ALSO - the Gamecube did actually have networking through a barely used peripheral (though I knew and loved it through Phantasy Star Online Episode 1&2):
