Hey!
I'm a noob at the site currently, and want to show you my work, and ask for a bit of help if it's not a problem!(I don't feel like making a new thread for the project until more stuff is done) You see, I'm making my third legit Mega Man hack now, which is going to be the 2nd most extensive MM3 hack around after kuja killer's Mega Man Odyssey It's not like I know too much about ASM, so I mainly solve the problems via other, simplier methods.That means to change something like AI, I need to look for every small piece of info on various sites. But enough said. My project is called Mega Man the Hedgehog Trap.Now that propably spoils one of the major aspects of the game:The stages are based on Sonic levels from the Genesis. Here's my Ice cap zone(Gemini Man stage) 
There are a few things though which I need to know to make this hack better. How can I change the text in the Dr. Light cutscenes?(The text table found on Datacrystal only works with Stage Select and things like that) And some info on the Boss AI...Either Doc(I guess if it's similar to the MM2 AIs) or normal, I don't even need to change all of them, but I'm tired of altering their rooms and that's it.(Insectduel's collection of adresses for MM4 is really great) I'm also trying to port some music from MM6,(using the MMC5 sound engine and kuja killer's document) if I can't do it, I might ask someone's help, or stick with sound channel pointer-based remixes. Thanks for any kind of help! |

Posted by Insectduel 1) I had picked correctly Scroll map position but still it doesn't work fine 2) Do you mean something like this: http://neshla.sourceforge.net/ Is it possibly to copy piece of megaman 2 hex code into megaman 4 hex code or is it harder. Is it any other tutorial like this one 3) So everything is based on copying codes from . nsf into .nes file or i have to use some programs ____________________

Posted by za909 from the 4th page of this thread: Posted by kuja killer plus some stuff from me: http://acmlm.kafuka.org/uploader/get.php?id=3917 as for text, the game uses two separat text tables, the one on datacrystal and the following: 00 empty 01 0 02 1 03 2 04 3 05 4 06 5 07 6 08 7 09 8 0A 9 0B A 0C B 0D C 0E D 0F E 10 F 11 G 12 H 13 I 14 J 15 K 16 L 17 M 18 N 19 O 1A P 1B Q 1C R 1D S 1E T 1F U 20 V 21 W 22 X 23 Y 24 Z 25 r 26 . 27 ' 28 ! 29 ? 2a : 2b , i hope that helps a bit |

Ah man, i figured my text editor on the MegaFLE level editor that i never finsihed, would of come in handy for people eventually.  You can view all the games text for megaman 3, 4, and 5, but couldn't edit any of it cause i grey'd out all the boxes.
It was only because i could never figure out how to do that stuff in visual-basic. About being able to edit text, and insert it back into the ROM properly. every time i tried, it would completely overwrite some totally random place in the rom and literally destroy it, that's why i had the boxes greyed out.
About dr light - the scripts there start at $1C215. Load a table file in the hex editor with the fceux emulator, and you'll see dr light's scripts on the right side of the hex editor for you to edit. 
oh and pratieus - you made an accident in your link  yours still links to mine, ya forgot to put your ID number thingy |

Posted by kuja killer Thanks for the emulator tip.I usually use other hex editors because I don't really hex edit that much(at least I didn't use to) By the way, do you happen to know a good hex editor that has a Find & Replace command?I'm using Cygnus and it seems to replace only $100 bytes of data at once(which really screwed me over when I first attempted replacing a music track) |

Hmm...so music-wise.Can I just insert a song from a .nsf file if it has 4 sound channels / is ripped from a game that uses the MMC5 Sound engine? |

I've got some questions about Mega Man 4 hacking:
1. I would like to know how to delete effect of rain in toad man stage and make that Mega man would not go behind background (normaly he comes behind rain but i want to make that he wouldn't go behind because i've changed background). 2. I've changed sprites of ring boomerang into magic card from MM&B but i want to know how to do that cards would go up like in MM&B (i've seen on Rockman 4 M that ring can be shoot in any direction) 3. How to change text in boss screen and weapon screen 4. If i make boss again (i mean i want to make refight with him) what number in hex code i should change Thanks in advance ____________________

-------------
http://www.a3share.com/members/1119/sdfsf.PNG the text thing is easy, just open megafle level editor, click the scene screen mode checkbox on the main window so its checked...and it's literally the first thing you see before anything else, the stage select screen you can edit. ------------- about rain in toad, darn, sorry wish i knew. it was documented fully from infidelity once before along time ago, but i dont got that doc anymore. ------------- ring go up requires a little bit of custom asm coding, i dont feel like going on a mm4 rom and seeing ------------- not sure about the refight boss thing, dont feel like checking. -------------- sorry for only answering 1 of your 4 questions at crist_93
-------------- za909 - yea, can copy-paste songs between mm3-6, and whatever other nes games use that engine...but the annoying hard part is that all the dozens and dozenssss of "instrument" pointer numbers have to be changed to other numbers...as long as the game has duplicate instrument settings as another game, or else it's going to sound all screwed up. if certain instruments dont exist like between megaman 6 and chip'n'dales or whatever, then they gotta be made custom..which sucks. |

Posted by kuja killer The really annoying problem is that I can't find a good hex editor with a proper replace function.Most of them don't even seem to have any kind of that, and Cygnus only replaces $100 bytes at once, when the song I want to copy-paste is $270 bytes long |

Some new questions:
1. How to make that it will be eight rooms and in everyone will be diffrent boss refight (i mean how to make wily stage 3 working same as wily stage in MM&B that you're fighting with bosses but there's no teleports). For now i can only make 2 fights - after second screen don't want to scroll and boss is same - drill man. 2. Is it hard to edit assembling blocks. I want to make my own piece of map where you have to jump throught them. 3. What pieces of hex code ar about boss battle. I mean i would like to copy hex code of for ex. fire man from MM1 or gemini man from MM3 and make that it will work on MM4. If it's possible will it work with weapons. 4. Where in hex code are abbitles of weapons. For ex. i want to make that drill will fly longer before it blow up or ring would stay longer in one place. ____________________

Posted by Crist_93 3. No you can't just "copy" weapons from other games, it doesn't work that way. |

Posted by za909 So you're using GFX for Sonic! Try downloading the pirate NES ROM called "Somari" (Based on Sonic 1). |
