What they did
benjedwards spent a few days with Claude Code getting a native port of Tetris DX from the Game Boy Color running on the NES using the MMC5 chip; it plays and sounds like the original.
Result (as claimed)
A classic running on hardware it never shipped for.
Tools they used
Cost: Pricing depends on the tools you pick; check each official pricing page.
Set it up
Write a one-page brief
Describe the app in plain words: who it is for, the 3 core screens or actions, and what "done" looks like.
Start the project with your agent
Open Claude Code and paste the brief. Ask it to propose a stack and a file plan before writing code.
Build one slice at a time
Ship the smallest working flow first, run it, then add features one by one. Commit after each working step.
Test it like a user
Click through on desktop and phone. Ask the agent to add basic tests and fix anything that breaks.
Check security and ship
Keep keys in environment variables, check auth and database rules, then deploy and share the link.
Copy the full setup prompt
Paste into your agent and it will walk you through the setup, asking before anything that sends, posts or spends.
