An NES CPU compiled into the weights of a stock Qwen3.5 model
nesformer compiles the NES's 6502 CPU (plus 2 KB work RAM) into the weights of an untrained Qwen3.5 model, so the model 'executes' games by predicting the CPU's execution log one token at a time. A host program handles graphics, controller input, and interrupts, and demos show Super Mario Bros. frames generated entirely from the weights.
Why now: It's a novel, mind-bending follow-up to Qwenputer (which ran CHIP-8 and RISC-V in Qwen weights) — running a working Nintendo in ~1GB of model weights — and it got attention on Hacker News with playable demos.
Who it is for: Curious ML and emulation enthusiasts who want to see LLM internals used as a general-purpose computer rather than a language model.
