[NES] Super Mario Bros.: Two Player Hack – Original game with two players simultaneous mode

Although Super Mario Bros. is a long lived classic video game, it also has many limitations. The most obvious regretful design is: the two-player game mode in this game is actually a two-player game in turn, rather than a two-player gaming at the same time. In other words, it is only after one player dies that it will be another player's turn.
