If I had the source code I might be able to pinpoint the problem… I know a little Visual Basic 2008/2010, and I think it might just be poor programming that's easily fixable, like a typo in the code that the VB dictionary didn't pick up because the typo meant something else… You know. :P

I think that Sappy is, to put it simply, a really sappy program all around. Sappy doesn't work on Vista (which was released in 2006) saying that you need some VB libraries. If you install those libraries, you get another crash, even if you're running XP. So my conclusion of all of this is that improper programming etc. caused the conflict between certain VB libraries (pre-included in some version of the .NET framework) and Sappy that the program can't handle. I also don't think that Sappy is designed to handle plug-in DLLs, so there's no solution there either.

My answer to all of this is to do a complete re-write of the entire program from scratch, and distribute it as Sappy x.x.x Mark 2 or some such, or at least do a beta for the new release. Other than that, I honestly don't know what to tell people who experience crashes; My Sappy 2005 and 2006 both crash on their own (they'll recognise an unsupported ROM like Red Rescue Team, but still crash when loading Ruby for instance).

Most crashes are because of dependencies and other issues, Some people from the Fire Emblem hacking society have come up with this

It's been modified, and works perfectly in Vista, and has some new features. :)

I too have the "Can't find file MPlayDef.s for inclusion" error.

>I have MPlayDef.s in the same folder as my .s file to be assembled
>I have the newest version of sappy (that supposedly fixed this problem)

Can anyone help? Thanks

I can hear music hacking into hacking into the music but I can not cycle to how to make it cycle?

Even though I copied the three ocx files to C:\Windows\System32, I get the runtime errors regardless.

EDIT: Oops never mind... I forgot to download and install Sappy 12 first.

Just for information: Just copying the files doesn't work because the files have to be registered in your Registry and the Sappy installer does this for you ;-)

Download links for Sappy and Midi are down. :( Solutions?

Unfortunately, no versions of Sappy (That I can acquire) are compatible with Windows 7. I instead use Song Inserter, but I have no clue how to use it. I have a voice group offset I want to use (0x43B8A0) but I do not know the 4 byte header for the Wild/Trainer battle music. Does anyone know these?

I tried converting the .midi file to the .s file, butwhenever I do, the .s file doesn't show up. Help me out here?

Really nice tutorial Magnius but i have a problem when i put my midi file in Mid2Agb folder i open Mid2Agb folder i found no.s file for my midi plz any help and sorry for bad english

If you're having problems with the VBAL error or just couldn't run Sappy on Windows 7, I've added a link at the bottom of the first post, that will fix that.

Also, the "Rom Tools" link with Sappy and Mid2Agb has been removed. You can now get Sappy and Mid2agb here.

hi Magnus
I found a technique for hacking gba music

it's simple with anvil studio without Hexad so I want your opinion on my youtube channel: TheFredWTF
Sorry for my English :)

It keeps crashing when I load a rom.

For those having trouble with syntax error #1002, that just means you are typing the wrong offset in the SECOND BOX when assembling the song. You should type an offset with a lot of free space, as long as it isn't higher than 0x900000. anything higher than 0x800000 should work.

I get a strange error. Sappy 2005 will do everything--compile, play, but it compiles bad. Once it is bad it crashes when it plays and doesn't show the header and stuff. There is no apparent way around this! Please help.

Oh wait, not higher than 0x900000...

When I try to run Sappy, I always get a window that says

"Run-time error '339' component 'vbalCbEx6.ocx or one of its dependencies not correctly registered: a file is missing or invalid",

so I can't even open Sappy.

So can anyone tell me what I'm doing wrong?

Edit:
I would like it if someone would answer my question.

Edit#2:
Does anybody read this thread anymore because I've been waiting for an answer to my question for over a week now and I am getting impatient.

Edit#3:
It seems like I'm not going to be getting an answer anytime soon so I'll wait and see if anyone will freaking answer for crying out loud!!!! I'm a very impatient guy and I expect an answer when I ask one, so can ANYONE just tell me what I'm doing wrong upon opening Sappy!?!? To put it simply, what does this error mean and how can I fix it? Oh, and I tried the link above and it downloaded but it still showed the same error, oh, and I'm also running the program from a sandisk flash drive, so if that is the problem I would like to know how to make it portable from a flash drive. Sorry if I came off as rude but I get impatient and I tend to get overexcited.

Edit#4:
I didn't realize this but I accidentally added 2 links in my last edit, sorry...

How do you change the tempo of a song in Sappy permanently? I'm trying to slow down a song from 120 bpm to 60 bpm, but the changes only occur while I'm playing the song.

Dude, calm down... If it asks for a file, google it and download it. Put it on the Sappy folder. If another error pops up asking for another file, download that one too. I had to download about 3. Usually that stuff happens in Win7 64bit. I only downloaded the files Sappy asked for, but you can try download the whole Visual Basic Runtime, just google it.
If you're still having problems with Sappy, google for Sappy 2006 mod 17.1. Works like a charm.
"I'm a very impatient guy and I expect an answer when I ask one" - You're not going to get all the answers to the questions you ask all the time (in life in general). Work on your patience my friend... learn to tolerate mistery and uncertainty :)

The way I'd do it: Rip the MIDI, edit the tempo, reloop it and insert it again. Trying to change the tempo in hex or anything of the likes would be a pain in the butt and really messy. Changing the tempo in Sappy does nothing, only slows the song down for replay.

I know that I need to, but I'd been waiting for an answer for a long time and this is the first time in 2 months since I've been on here but I am only 16 years old, so it might come off as rude. I'm just glad I finally got an answer and I'm going to try that now, thank you.

Edit:
I got the same error again and so I then went into the compatiblity settings and made it where it should work in win7 through xp compatibility settings and it still showed the same error again(of course it did). Might there be something else wrong because I did almost exactly what you said I should do and it didn't really work out for me so I may need to move the missing file to the hard drive of one the computers I'm using or just wait until later to worry about the music, I've only been rom hacking since March or April...

Edit #2:
Well, I got it to work, but it crashed when I tried to insert a .s sound file, so I decided to delete the program because I can't figure out what the hell I'm trying to do, and stick to what I am best at, Map and Tile hacking, at least until I can find someone to help me with this that I actually know so that the hack will get finished quicker,(and easier) so I can hack other games.

I'm trying to change the battle music for the rival in emerald, I'm using sappy but the songtable isn't there altough the songs are, what number in SAPPY is the rival battle in emerald?

Which language do you use? The song order should be the same although the offsets of the songtable differ. The US version fon Emerald should be in the list though. If you want to I can sent you my sappy.xml with correct offsets.

Hi there! I don´t know what to do if i have windows xp and how do i make it to wild battle theme?

Wow, this is my first post in a while. I know that this may be off topic, but I happen to be very good at nds music hacking, and I might be able to help with that if you like. :)

I have a problem when I play the game.I try to replace the introduction music but it ends up being very high pitched.I need help

Thank you, this is a wonderful tutorial! But I'm wondering, how can I make MIDI files?
