What is rollback netcode in fighting games?

Fighting games make up one of the most beloved genres of all time. From the emergence of 2D fighting games in arcades such as Tekken and Street Fighter to the creation of Mortal Kombat, Super Smash Bros, and Marvel vs. Capcom for consoles alongside the introduction of 3D base models, fighting games can really bring out the excitement in fans. The thrill also comes when the lives of the characters the players are using are on the line, with the last hit sealing the deal for the winning player.

But producing these games to give the most intense and action-packed gameplay to fans is not easy. It requires months or even years of blood, sweat, and tears to bring a game to life, especially for fighting games since their gameplay is more real-time based to savor every moment of action available in matches.
