Has this ever been done? or does anyone know of any document with a detailed description of how Simon was programmed? |

Hmm... ineresting, I've never really thought of changing Simon himself much. I think I changed him once on accident. Anyway, I've never seen any document on such. Shouldn't be too tough to find out though.
Typically, a good of finding the location of such data is to check routines that involve pushing certain controller buttons, and as far as I can tell with the NES, its zero page LDA F5 or F7. In hex, it appears something like as A5 F7 29 XX, with XX being a value for certain buttons. Beyond those, you can find things that happen if you push that button. |

Oh, so it's F5 and F7 in Castlevania as well? I've seen these addresses in a few other games. Maybe it's a de facto convention, or because it was the same programmers? As far as I know, it would be F5 for buttons pushed, and F7 for buttons held, one bit per button. F6 and F8 for the second controller...
Of course, understanding basic assembly is a minimum when you want to change the behavior of sprites, physics and such... |

@blackhole89: I want to know the mechanics behind Simon so that I can recreate him exactly in GameMaker and possibly also edit an old hack of AjD I did way back when. This would include physics and anything else that involves Simon directly.
@Optomon: Thanks for the info. If, like in your CV hack, the main character isn't Simon or even a Belmont it would be cool to have altered physics. Also, I recall there being some GameGenie codes for altering Simon's jump height. Those may be helpful to some small degree as well. @Trax: That would make sense. So I guess I'll have to bite the bullet and learn some basic assembly. blech...! Had to happen some time I 'spose. Thanks for the input guys! =) |

That sounds like a good idea to start off while try to verify the exact values from the asm. Thanks! |

I remember playing a Castlevania hack in which Simon was allowed to move while cracking the whip. That's the only physics hack I've seen on the main character. I don't remember the hack's name, though... |

The CV1 editor stake has a patching system and that is one of the effects that it can enable. Thanks for reminding me about that! |

Can anyone recommend any good resources for learning ASM for the NES? |

There's that document taken on romhacking.net :
