Hello guys :)
Today I would like to show a little research already been done in the past by an English hacker, still we don't know how he did it because it has not issued any tutorials relating to it.
The research involves an additional block tile to the two normal editable with advance map where we reconstruct the tile in the levels "above/below".

hope you like it :)
Bueno, sé que esto es un poco viejo, pero shinyquagsire hizo algunas investigaciones sobre este, así que me pareció buena idea publicarla aquí:
