I hate this headline, because it discounts the massive amount of accumulated human work that went into this, too. Just read the attribution part:

It’s not like someone prompted “port this game” into a chatbot for a lazy port. It needs extremely specialized skill (hence the long list of attribution from PS4 emulation projects), and I suspect the LLM part just provided the 'bulk labor' that small hacking groups otherwise couldn't pull off.
