A hack of Super Mario Bros. for the NES which combines both the first game and the sequel (SMB2 The Lost Levels) into one game, after World 8 the game continues right at the start of SMB2.
The game physics are more in line with The Lost Levels with the floatier bounce and you get to choose between Mario and Luigi at the start, so it’s more similar to the sequel, this is my personal definitive way to play this game.
