I remember in Super Mario Bros. the original, in world 1-2, if you didn't go to the warp zone but instead went to the pipe leading to the exit, don't go through the exit. Instead, break the 2nd and 3rd blocks on the ceiling from the right, mario will be able to go through the first block, into the warp zone. Enter a warp zone before the numbers appear over the pipe and you will enter the "minus world," which is an underwater stage from which there is no return. One of the first games for Nintendo has the most memorable coding error. Anyway, SMB3 was great, but SMB2 is the best. I think it's the most underrated of all nintendo games.
