@joyu - Doing that takes you to -1, not world 0. the negative world was
just a repeating underwater world.
Also the the first and thrid pipes took you there. The middle one took
you to lvl 5. No doubt due to the fact that on another warp lvl with the
single pipe in the center that took you to 5. (note that on that lvl, if you
do the walk thru wall trick to get to the single pipe in the middle it will
still take you to lvl 5)
Also to note you don't need to stand on the very edge of the pipe to
get through the wall. You can almost stand anywhere on the pipe.
I think you need to be squating and jump backwards.
I have two 'movies' i made that play on nesticle showing how to get thru
the wall. goto
http://members.tripod.com/kalen/nes.htmlTo use these files, click esc or space bar while in nesticle. goto CPU->nes movie->play
and type in the file name. Press stop once you see mario went thru the wall to end the
movie if you want to get to the warp area. Or press alt-p to pause it then stop the
movie. (I only made the files as a demostration for myself if I later on wanted to know
how to get there. So I jump out and try again and again)
Also it does look like a glitch that's not supposed to be there. It would've
been too hard for them to have done that on purpose and it's a glitch
they would eaisly have missed.
This is the whole pic of 0-2. (for me 0-1 is the start lvl 1-1.
