Dolphin Progress May and June 2020
Slightly related, a couple of weeks ago a guy named Fizzi released a dolphin build with rollback netcode support for Super Smash Bros Melee, making it a game with better netcode than most current big name fighters.<p>The way he implemented it is insane, he had to reverse engineer a way to generate arbitrary game states in game, as using dolphin savestates was not performant enough.<p>He's also added other amazing features, like in game matchmaking, or my favorite, being able to stream a game state through the Wiis ethernet port, so two players can be competing on original hardware while a stream setup upscales that footage in realtime to 16:9 4k through Dolphin, and also generates real time match stats, saves replays... Incredible stuff.<p>Here's the project page: <a href="https://slippi.gg/" rel="nofollow">https://slippi.gg/</a>
