Mega Man 2 hack help

Post by chupon »

Sooo like 10 years ago a buddy of mine composed and re-did all the music to Mega Man 2 and Mega Man 3. Even menus, password screen, and opening pan up the skyscraper. It ruled. I'd love to post the mp3s and share. I'll get his permission first. Now to my real question and cry for help.

How can I or anyone go about writing / hacking / modding a rom / iso / something else to get the game to play with the music he wrote. I'm sure in today's day and age it can't be that hard. I doubt I could put it into an actual NES cart but that would be the best. I bet someone could make a rom but doubt emulation is the way to make it work because the music is not MIDI.

Anyone have any clue or can anyone point me in the correct direction?

I wanted to stop here and ask first before looking on the web myself cause I thought someone here could help. I did a search before posting but couldn't find too much. Any help would be appreciated! Oh yeah - I'm an architect not a coder so I don't know any computer languages.

That means it's not possible to put it in the original versions of the games, because the NES wouldn't be able to handle them. Your best bet would probably be to hack a compilation title, which is harder. I'd imagine the Rockman compilation for the PS1 is your best bet, but it's in Japanese. You might have to go for the Anniversary collection, which would be excruciatingly hard to hack.

Unfortunately, that's step 1 of hacking. You're definitely going to need to know code, or someone else who can code for you. What language, I'm not sure.

Your best resource is Romhacking.net. Those guys have all kinds of tutorials on getting into hacking. But as mentioned you will need to learn programming.

Well there is a plugin for a Genesis emulator letting it play MP3 files in place of the music in Sonic 2. So if someone knew were the music was playing in ram theoretically they could mute it(while keeping all the sound effects), and just play an MP3 in it's place.

Aww crap. Didn't read your post correctly before.
Maybe the music could be converted into XA streams and somehow hacked into the PS1 discs?

Well, I'm not gonna let the whole post I made go to waste even tho it is now moot.

(disregard this section)

Read the included file here:
http://nesdev.parodius.com/bbs/viewtopi ... dfa709129e
Grab the latest files off TSSF's remakes directory here:
http://tssf.gamemusic.ca/Remakes/GIBStuff/
TSSF included a utility called S3M2NSF which will allow you to use Impulse Tracker, Screamtracker or one of the other multitrackers to make tracked music into a NSF. There are also a few ways to convert a MIDI File into a Screamtracker file (S3M). The project isn't impossible, but would require an immense amount of work to convert the music in an accurate way (depending on the original source files being converted of course). Using automated utilities will only do so much - using default settings, and making each instrument into the approximate best-match, then just running the files through as-is would definitely sound like crap. Getting the original sounds to be properly interpreted by those utilities at each step of the way requires a lot of skill.
What would probably be easier, and faster would be to load the midis into an editor, and manually transfer the piano-roll notes into Famitracker. Unless you're actually good at composing music using a tracker you may want take the time to do it the other way anyway tho, just tweak all the results to sound closer to the original.
Probably your best bet would be visiting the forums on http://nesdev.parodius.com/ and http://www.romhacking.net/ - those guys have a bunch of the stuff figured out already, and will be your only option to get the NSF file injected back into the rom. If you need some help with the midi to tracked music converting part I may be able to help there as I've messed around with that end of the conversion process quite a bit, and know some tricks and programs that would probably be useful.
