Rollback netcode now available for the entire Nintendo 64 library

The Nintendo 64 is an iconic console that has produced a wide range of games, including the beloved Super Smash Bros. With the latest update to the RMG-K emulator, the entire Nintendo 64 library is now compatible with rollback netcode, a major step forward for competitive players.

What is RMG-K?

RMG-K is a fork of the original RMG Nintendo 64 emulator and received a major update (v0.9.4) on May 14, 2026. This update allows players to use rollback netcode not only in Super Smash Bros., but also in other multiplayer Nintendo 64 games. This development is especially important for players who want to compete without the drawbacks of delay-based netcode.

Benefits of rollback netcode

Rollback netcode offers significant advantages over traditional delay-based netcode. In a safer and more responsive setup, rollback netcode predicts the most likely input in a given situation and “rolls back” to an earlier frame if that prediction turns out to be wrong. This results in smoother matches, even on less stable internet connections.

Why this update matters for players

This new functionality makes it much easier for players to compete in Super Smash Bros. Until recently, there were only two options: bringing a real Nintendo 64 console or using an emulator with less effective delay-based netcode. The introduction of rollback netcode dramatically changes the experience, especially for those hosting matches or taking part in tournaments.

Conclusion

The introduction of rollback netcode for the entire Nintendo 64 library provides a valuable option for players who want to compete, especially for the passionate community around Super Smash Bros. With this, the RMG-K emulator has made a significant contribution to the accessibility and quality of multiplayer gaming on this classic console.
