Got two of ’em
Super Mario Bros – The Lost Levels is actually the original Super Mario Brothers 2. Since this version was thought to be too difficult for US, we got the alternative, until it was repackaged in the SNES version. All in all, it’s a pretty difficult game, and I guess it might’ve made a few 7 or 8 year old kids upset at the difficulty. Ah well. Anyway, here’s a few vids of the game. The first one is a tool assisted run, cuz DAMN IT, the player should’ve died 100+ times in this vid.
In this one, these are the A-D levels from the SNES version
