Drew Breunig 将 NES 6502 CPU 模拟器烘焙进 Qwen3.5-4B 权重

dbreunig/nesformer（via）受 Divyansh Agrawal 的 qwenputer 启发，Drew Breunig 将一台可运行的任天堂娱乐系统 6502 CPU 模拟器烘焙进了 Qwen3.5-4B 的权重中。现在你可以在 Qwen 内部运行《超级马力欧兄弟》等 NES ROM（速度非常慢）！

在Hacker News 的一条评论中，Drew 披露了他用来构建该系统的 Opus 5.5 提示词：

Read this article and any relevant source code: https://divagr.com/blog/qwenputer. Then explore if you could emulate the chip and ram in a Nintendo Entertainment System (as people do today with FPGAs in MISTRs) using this technique. If so, what size model would you have to build and if you could use smaller faster ones, could you get it to be at the standard clockspeed.

随后是：

I think we should build it! Just for fun. It's okay if it's not fast. We want to be able to have the weights, and a cli to run them that we can point at a ROM.

显然，Opus 找到并使用了 Christopher Pow 在 15 年前发布的这套 NES CPU 一致性测试集。
