What is RetroArch Netplay and How Does It Work?
RetroArch Netplay lets you play multiplayer retro games online by connecting your game to your friend’s game.

Netplay uses a special system called “rollback” to keep games smooth, even if your internet isn’t perfect. It’s like hitting rewind and fast-forward to make sure everyone’s game stays in sync. You can host a game (be the leader) or join a friend’s game using RetroArch’s lobby or their internet address.

What Do You Need for RetroArch Netplay?
You need 5 things to play RetroArch Netplay successfully. Here’s the list:
- Same RetroArch Version: Everyone must use the same version of RetroArch, like 1.21.0, or it won’t work.
- Same Game Core: The game emulator (called a “core”) must be the same, like Nestopia for NES or Snes9x for SNES.
- Same Game File: You and your friend need the exact same game file (ROM), like Super Mario Kart (USA).sfc. It’s checked with a code called CRC32.
- Internet or Wi-Fi: You need a good internet connection or local Wi-Fi. The host might need to set up their router for online play.

How Do You Set Up RetroArch Netplay?

Step 2: Set Up Your Network
Go to Settings > Network in RetroArch. Turn on Netplay and use port 55435 (the default). If you’re hosting, check if your router allows UPnP or open port 55435 manually. For private games, add a password or hide your game from the public list.

Step 4: Host a Game
Go to Main Menu > Netplay > Start Netplay Host. Pick your game. You’ll see “Netplay will start when content is loaded.” Your game shows up in the lobby at lobby.libretro.com unless it’s private.
Step 5: Join a Game
If you’re joining, go to Netplay > Refresh Netplay Host List, pick a game, and press A (or your confirm button). Or enter the host’s IP address manually. Make sure you load the same game and core.
Step 6: Make It Run Smoothly
In Settings > Network, try setting Delay Frames to 1–3 to reduce lag. Use Relay Server if you can’t open ports. Set up controllers in Settings > Input so everyone controls their own character.
Check these steps with your friends to avoid problems and start gaming!
