CHIP-8 matched the instructions on the first pass

What was done
On 17 February 2026 tetsuo writes that Grok 4.20 runs four agents on every prompt. They split the problem, build in parallel and merge the result. He pointed them at games all day. The tasks were Tower Defense, Mini Factorio, a CHIP-8 emulator and a roguelike shooter. The emulator surprised him. Four agents matched the opcode set on the first pass.
How it went
The opcode set matched on the first pass, according to the post. The other three games are named, without a matching result.
Worth knowing
The post does not say he played the emulator. It does not say the other games were finished.
How to do it
- Name the game, and ask the agents to split it into parts they can build side by side.
- Read what was merged, and try the emulator locally.
- Do not publish until you say yes.
Try it with Grok
Let the agents split [game] into independent parts, build in parallel and merge the result. Show me what was finished. Do not publish until I say yes.
Replace text in brackets with your own.
Done when. You have tried the result locally, and it was not published before you said yes.
Safety rule. No publishing until you have said yes.
