DV,
Great! If you find it, may you send me the ASM?
Thanks! |

not right off, but there is no table or addresses it reads from. It takes the Y position and does some operations on it then spits out an X,Y location on the map and a map screen. It's rather confusing how it does it, but I might, if I have time and can find it, create a small hack so that it basis the calculation off something more simple so people can edit it. |

But there is a routine, right? What other addresses in the ROM did the routine read and/or what calculations did it perform? You don't happen to remember where the ASM might be located, do you? |

In every pipe level, there is but one sprite, whose position differs for each enemy data offset. The y position of that sprite in the level seems to be of great import (though not the x position). A particular y position seems to signify where on the World Map Mario will emerge when he leaves the pipe level through either the left pipe or the right pipe (each y position has a different value for each), but it seems to follow no pattern. Because of this, I believe that stored somewhere in the ROM there is a table of pipe locations, a table, I think, many SMB3 hackers would like to have. Does anyone have information on this? |
