Hi! I'm new here.....
You may not understand me, I'm from Peru and my english is not perfect....
Well.... I want to make a hack of MegaMan 3, and I need to add an intro to the game, is there a way to do this?
Thanks!

since there never was any intro originally in mm3 while all the other NES games did have one except for mm1 ...it would have to be all done from pure scratch, so that means you'd have to know NES ASM very well first before getting to even attempt such a thing.

sorry to disappoint.

The cheapest way I can think is to just copy/paste one of the Dr. Light cinematics to when you turn on the game, then edit the duplicated cinematic. Of course, you would have to find a way to do that, first by identifying the condition under which a Dr. Light cinematic occurs. Not sure how possible it is, I'm just speaking hypothetically.

Awww...
But, since MegaMan 3-6 run on the same engine, is it possible to "port" the intro from Megaman 4 to MegaMan 3???

not exactly, no.
the only thing that can truly be copy-pasted between mm3-6 freely with zero problems, is music and sound effects because the music engine for those games is purely 100% the same byte-for-byte so it makes copy-pasting music and sound between the games super extremely easy with no side effects.

but as far as anything else is concerned, cant copy-paste any other form of code between the games because the registers and stuff like weapon's life. enemies, level data...and all those things are not the same as each other.

Oh, I see..
Thanks, anyway, kuja killer....


Now, I'm getting annoying...... How could I port music from MegaMan 5 to MegaMan 3??

it's no prob. just will take some time and all.

first gotta plan out ..what song do you want to take from mm5 specifically...and then ..what song should you choose to want to over-write on mm3.

the main thing is like tons of jump's and pointers must be changed in the mm5 song in order to point to the correct places when pasted in mm3. takes a long time to find it all since there could be dozens.

i believe matrixz (author of megaman forever) has some program that can do it automatically so you would not have to hex edit it by hand ..i dont have such program though.

instrument settings have to be changed too, but that's tricky. overwriting those should not be done cause lots of songs may share the same sets.

uhhhh this all just involves needing to change the pointers mainly after copy-pasting it over first.

Wow... so, if I ask Matrixz for the program, there's a chance for me to get it?
I'm really itching for hacking MegaMan 3, but I need something to make my hack special
Thanks, kuja!

This is about the little program which fixes all the loop and jump pointers correct? I lost that, i don't have it sorry.

Oh... I see.
But, what happens if I just copy/paste the music without changing the pointers??
And... Is it possible to port the Charge Shot (as in MegaMan Oddissey) to a clean MegaMan 3 ROM?
Damn, I need something cool for my MegaMan 3 Hack....

to do things like that you need to know asm. probably not possible otherwise. altough, music is possible to change between mega man 3-6(and SOME other capcom games) without knowing asm. i have mannaged to, but it takes some time and might be hard
