Random: Smash Ultimate Rollback Netcode Mod “Proof Of Concept” Up and Running on Switch

Finally Smash Bros.

Back in 2020, a Famitsu columnist suggested Masahiro Sakurai and his team consider restoring the netcode for Super Smash Bros.but apparently, it failed.

While we’ve seen restore support in other fighting games on Switch, there’s a software engineer – called ‘DShad’ on Twitter – who has been working on his own Smash Ultimate recovery network code for the Switch emulator, for a while.

As spotted by EventHubs, this talented individual has now shown off their mod rollback running on a modded Nintendo Switch – showcasing an online “cross-platform” match against a simulated version of the game. This was achieved on Switch by running the Skyline plugin system, which allows users to load custom code into the game.

It’s all just a “proof of concept” for now, and there’s still a lot to go through, according to the creator:

“Video is a technical proof of concept… I’m not saying keep your expectations low, rather keep it moderate.”

For anyone unfamiliar with the recovery netcode, here’s our previous recap of it:

… recovery netcode (as opposed to latency-based netcode) is often favored by fighting game fans for a more satisfying, faster online experience. Latency-based netcode delays game state updates until player input is received from wherever in the world they were sent and is therefore highly susceptible to network fluctuations and often results in an unpleasant experience for both players – not ideal in a fighting game.

In contrast, netcode recovery behaves differently; it logs when input is received and adjusts (or ‘rolls back’) each player’s concurrent game state to match. This can lead to players appearing to ‘teleport’ when receiving new input, and can also lead to synchronizing between each player’s games, but overall a great experience. smoother online experience.

In its current state, if you wanted to run something like this on your own system – you would require a modified Switch, and even then – there would be risks involved.
