nesformer compiles an NES processor into Qwen weights
What happened
A Hacker News post on October 31 shows nesformer compiling the NES 6502 CPU into the weights of the Qwen3.5 architecture, running games by generating an execution log token by token. The weights are untrained and the checkpoint holds 466.6M parameters at 933 MB. CPU, RAM and program ROM run inside the model; the host program handles graphics and the controller. Output frames from the bundled test game match a reference emulator. Only NROM cartridges work, there is no sound, and it runs 150–290 times slower than real hardware.

nesformer 将 NES 的 6502 CPU 编译进 Qwen3.5 架构的权重，以逐 token 生成执行日志的方式运行游戏。权重未经训练，检查点含 466.6M 参数，占用 933 MB；CPU、RAM 和程序 ROM 在模型中运行，画面与控制器由宿主程序处理。随附测试游戏的输出帧与参考模拟器一致，目前仅支持 NROM 卡带，无声音，运行速度比真实主机慢 150–290×。
