The delay-based code tries to synchronize the players’ entry times by forcibly delaying the faster entry. The game cannot start the simulation until answers from all participants are received, and at such moments it simply slows down.
In contrast to this method, the network rollback code tries to predict the login data and thus starts the procedure immediately. If the real data match the predictions, the game continues, if not, the developers have to figure out a way to disguise its “jump” to its original state.
It is not yet known when The King of Fighters XV will be released. The game’s creators have not even released an official list of supported platforms yet. So far, they are introducing us future characters, and the next announcement is scheduled for March.
