## Executive Summary
dbreunig/nesformer Inspired by qwenputer by Divyansh Agrawal, Drew Breunig baked a working emulator for a Nintendo Entertainment System 6502 CPU into the weights of Qwen3.5-4B.

## Why It Matters (Strategic Analysis)
Embedding hardware execution logic directly into model weights demonstrates the capacity of LLMs to internalize deterministic state machines and low-level instruction sets rather than relying solely on probabilistic text generation. This blurs the line between traditional software emulation and neural weight parameterization, highlighting unexplored computational capacities within transformer architectures.
