# Mario Kart 64 Browser Multiplayer

I recorded that Oliver Sauter created a browser‑based port of Mario Kart 64 that runs the original N64 game entirely client‑side, supporting real‑time online multiplayer and even allowing the game to be embedded and played directly within an X (Twitter) post.

- Playable in any modern web browser, no download required.

The port likely leverages WebAssembly compiled from the original N64 binary (via Emscripten) and uses WebRTC or WebSockets for low‑latency peer‑to‑peer networking, while the X embed utilizes Twitter’s iframe support to render the interactive canvas directly in the timeline.

Open questions remain about the exact network architecture, input latency handling, supported browsers/devices, and any legal considerations around running Nintendo’s IP in a web environment.

- Real‑time multiplayer sessions launch automatically every **30 seconds**.
- Private races can be created via a shareable link.
- The game can be interacted with inside an X post using an iframe/HTML5 canvas embed.
