Wow, I come back after 2 days to see this topic is of discussion still and if you think about it, it should be because no one has changed what Mario does besides shoot fireballs. I know it wont be as simple as using the same address for mario kicking and over writing the fireball throwing routine. |

O_o indeed. That must mean it's hardcoded to only have at most 2 fireballs on the screen at once. |

No, that's just the pointer to a handler rountine, usually. By that I mean it would point to something like this:
cmp #$01
beq xxxxxx
cmp #$02
beq xxxxxx
etc... |

- Fireballs don't count as regular sprites, they're separate entities.
- Mario wouldn't be able to shoot any shells if there are already 12 sprites on-screen, maybe less depending on the sprite memory setting (and believe me, if he starts shooting shells willy-nilly, they're gonna add up quick), thus making the powerup useless. Fireballs, being separate entities, are exempt from this limitation. Also, if too many shells were spawned right before the goal tape/sphere, it might not appear.
I believe a hack of this magnitude is beyond the current abilities of just about everyone on this forum. It involves a LOT more than just attaching the sprite generator code to the fireball routine... |

Wuh? That wasn't me, that was BMF. I'm pretty sure asking for someone else to find something doesn't count as finding something. And besides, IIRC the fireballs themselves are part of Mario, so it's not as simple as that, and simply making use of existing sprite generation code probably wouldn't help you too much (yeah sorry guys  ). You'd most likely need to write your own code.

As a sprite generator, look up the code for the bullet bill shooter, or the torpedo ted shooter. If you trace their code, you should be able to find out how to generate a sprite and set it's direction. |

It shouldn't be too hard to edit the code, of course, first we'd have to figure out exactly how sprite generators work, then the rest is just gravy. Of course it might turn out that the generator code won't function properly if used as a fireball code.
Hey, wait, how many of the subroutines required to do this are known?
Shell kick routine, where mario hits a shell and it slides forward, is that known?
Sprite generator routines, has it been figured out how they work?
Fireball routine, we know how to change the physics settings but are those part of the routine itself or is that address just referenced by the routine? |

Look at the very first post in the ROM Address thread. |

I suppose he means to make shells appear which travel along with its physics (falling down lower terrain, hitting obstacles, coming back when hitting a solid tile and so on) - that would be a weird thing if just changed the fireball's "graphics".
And since the fireballs turn, it might be very weird to see turning shells |

Ok. What I would like to know is the ROM address for Mario kicking a shell.
The reason I want this is because I want to see if I can use it to replace fire marios routine.
I will make a powerup where Mario goes around and kicks shells instead of shooting fireballs.
I have these ideas from Dhark Daiz Mario 3 hacks where he used other objects. |

I have absolutely no idea what you're asking for. Can you describe it a bit better? |

Anyone have the hex address I seek? |
