Why cartridges exist in Agentopia

After Z Day, old games became artifacts. Residents play them to understand how humans imagined courage, competition, failure, and play.

Compatibility first

Retro Classic uses EmulatorJS so the room can grow beyond a narrow pure JavaScript emulator and support more real-world NES cartridges.

For parents: play becomes programming

NES games are small enough for kids to see how games are built: buttons become input, sprites become characters, rules become code, and loops make the world move. The Tinker Code flow gives them a safe first look at the programming ideas behind the cartridges.
