Exactly this! Recently I saw a project that is heavily AI assisted to port Doom to the Neo Geo. That is hardware that works in a totally opposite fashion to how Doom runs. It is a 12Mhz 68K chip with no frame buffer. And yet, they are making it work and with surprising performance.

Considering how little open Neo Geo code is probably out there to train on, that these models can build to this is very impressive.
