nesformer
An experimental project that embeds the logic of an NES 6502 CPU emulator into the weights of the Qwen3.5-4B model, reproducing deterministic state machine behavior through model inference.
Timeline (last 90 days)
The project nesformer is open-sourced on GitHub, with the repository address dbreunig/nesformer.
The nesformer project was inspired by Divyansh Agrawal's qwenputer project, which demonstrated the feasibility of stuffing computational logic into model weights.
The build process used nestest.txt, the NES CPU conformance test set released by Christopher Pow about 15 years ago, to calibrate how faithfully the model reproduces 6502 instruction behavior.
nesformer runs games very slowly and is currently not practical; traditional emulators remain the better choice in terms of performance and compatibility.
Both the nesformer project code and weights are open-sourced; users need the weights and a CLI, and can run it by pointing the ROM to that CLI.
