   nesformer Compiles an NES CPU Into Qwen3.5 Weights

   The nesformer project uses a compiler to produce a standard Qwen3_5ForCausalLM checkpoint containing an emulated NES 6502 CPU, 2 KB of work RAM and cartridge program ROM, rather than training the model on those weights. During play, the model predicts the CPU execution log one token at a time, while a host program handles rendering, controller input and vblank interrupts. The project reports frame-level agreement with a conventional 6502 emulator for its bundled tests, but execution takes roughly 1–6 seconds per frame, and the PPU and APU remain outside the weights.
