Minus World in All-Stars? (Feb 20, 2014)

Nope, I'm afraid not. But there does seem to be a remnant of the buggy warp zone coding. The default warp zone in SMB is World 5. So, in the NES version, if you go glitch through the wall in 1-2 and go down the middle pipe, the warp zone defaults to world 5. "5" will appear over the middle pipe, with nothing over the other two. This partially works in All-Stars.
