Converting Midis to GBA format

[Supreme Dirt]

Alright, if you don't have Midi2GBA, you will have to google it. I cannot post it here do to certain... legalities.

Anyways, here is the very simple tutorial which is known by a surprisingly small percent of hackers.

1. Open the folder containing Mid2AGB.exe
2. Open the folder containing the midi to insert
3. the midi to the same folder as Mid2AGB.exe
4. Drag the midi onto Mid2AGB.exe, as if the program were a folder
5. A DOS box should appear and then vanish, and the midi (in my case A-tomb.mid) should appear as A-tomb.s, replacing A-tomb with the name of the midi.
Then, just follow the instructions in Sappy's help file.

Happy ROM Hacking

As I'm aware, Sappy's *.s files represent a single MIDI channel, so shouldn't the MIDI you import only use one channel? Also, what would we need to do in order to make the music loop?

And MIDI's Are....What exactly?

And MIDI's Are....What exactly?

Oh come on... If you don't know what MIDI's are, why are you even looking at this thread?

[cooley]

AlRight, Alright, I was Just Kidding. :)

[Martin Yiu]

Okay, we can figure out how to split the single *s file to multiple ones by usin Green Charizard's music editing tutorial. But one thing, a little bit more advanced, is here staying without the coverage of either tutorial. How to make song loop, and then, how to change instruments by hex. I still didn't figure this out, so if there's someone capable of doing so and active enough to make a tutorial, I would ask you to make one to make life easier :P Thanks, anyways. And about your tutorial, you should specify more details to each step, tell something about theory, what the program exactly does and WHY IT'S ILLEGAL TO HAVE IT.

[Prof. 9]

It's illegal because it's part of the actual DevKit that Nintendo uses.
At least that's what I heard >_>

Well, you heard right. MID2AGB is part of the official Nintendo GBA devkit, and so is illegal to distribute.
As for who could improve this tut (how to loop, getting the right instruments, etc.), Zel is getting G/S/C music for ShinyGold from birthofdna and Magnius, so I assume they know how to do that... IDK how active either of them are, though.

[zel]

In fact guys, the problem of looping is something that everyone has. So we are all in the same situation (so far, all I can do is extend the length of the music by looping the midi by hand before inserting... Of course this means using more rom space, so if there is a way to make a loop, at least using hex, it would be interesting to hear about it)

[Mastermind_X]

... that isn't known? I think, I saw a reference or something. Well, I'll have a closer look on it, if I find the time, but I think it's not that important.

[Supreme Dirt]

I'm currently working on finding a way to make music loop. I can loop it, but it sometimes crashes the emulator. I will update my tutorial when I find a way.

And I deal with the single track *.s thing by using Anvil Studio (anvilstudio.com) to edit the midis and save each track to a single file. I then combine them in hex. A little bit complicated, and I may post a tutorial.

[SephirothX]

Well, you should have at least mentioned that in the fist place. -_-;
Good luck with the looping!

[Teh Baro]

Kawa told me long ago how to loop. It was editing the *.s file by hand, adding some stuff. Anyway, when I tried to import it, somethign went wrong

-I'll look at the old chat logs for all this stuff

EDIT:

.byte GOTO
.word targetlabelorpointer

In notepad, open the .s files and write it, changing the targetlabelorpointer for a label you insert.
Example:

When more stuff in the game is done (and I have more free time, I'll try to hack music again... I think I know what went wrong last time...

This is my .s file, what's wrong?

[zel]

I have been editting a midi and I didn't have any problems making it loop (so your example worked for me, Baro), the problem about it is that you need to make that for each track, which will get kinda tiring if you have to do lots of music (I wonder if there could be a better and more direct way...)
The other problem I seem to have is when the tracks don't seem to have the same ammount of @ values. Say I have one track that ends at @040, while other at @036, so if I try to make them loop with the GOTO command before the FINE, they end up (obviously) looping in a way the tempo between the tracks gets destroyed... How is the exact way in which I could make all the tracks have the same ammount of @ values? (And would that work to make all the tracks coincide again?) Is it done with?:

[Martin Yiu]

Oh great! Someone making the way to loop! Good luck boys, I would help you but I am total n00b at these things (but I am not that n00b in the other parts XD) so I'm crossing fingers ;)

~Martin

[Supreme Dirt]

alrighty. I now see why the emulator kept crashing.

[thetribemaster]

Aha here comes the part that sucks... One of my friends showed me once but I forgot and he moved. If I see how again I'll report back.
Anyway... Thx for the tut man. Its a great one!

[mcrc]

this is great i can start up making music for hacks again, i'll try out the looping thing tomorrow
