Could you build this?
No Compiling a CPU into the weights of a transformer is a novel research-style experiment. It requires ML interpretability and training expertise plus substantial compute, and vibe coding cannot substitute for that.
What it would actually take: The project would need a precise instruction-level encoding of NES CPU state transitions into a model's weights, likely via fine-tuning or weight engineering on a base model like Qwen. It requires expertise in mechanistic interpretability, model training, and emulator correctness. Substantial GPU compute and research iteration are needed.
