Help with detuned song - Custom Music

Hello, after searching in YouTube for the song A Great Game of Chase from VIP Mario 5, I found a video that contains the download for the SPC file: https://www.youtube.com/watch?v=4CxX3BSg84A
However, unlike the SPC distributed with the VIP Mario 5 SPC pack, this SPC was generated by AddMusicK, because the one included with the VIP Mario 5 SPC pack only plays the first note of the song, but this SPC that comes with the video plays fine. This means that the author of the video has the txt file, but he doesn´t distribute it
I used AddMusicK 1.0.X SPC Disassembler and it worked, I got the txt file and samples. I generated a SPC with AddmusicK port mode and while most of the music plays fine, the channels 5, 6 and 7 are detuned for some reason.

Here is the txt file and samples: https://bin.smwcentral.net/u/36104/A%2BGreat%2BGame%2Bof%2BChase.spc_disamk.zip
Here is the SPC I downloaded from the YouTube video:https://bin.smwcentral.net/u/36104/A%2BGreat%2BGame%2Bof%2BChase.spc
And here is the SPC generated by AddmusicK, which has the channels 5, 6 and 7 detuned:

Any help for fixing the detuned channels would be appreciated

I will check out if my disassembly tool has bugs or something, but at the mean time, if Vipper team decided not to distribute the source file of these ports, there is a reason behind that.

If you planning to use that song in your hack and submitting to SMWC, no, it's not a good idea; and your submission will violate site rule C6, because you don't have permission from Vipper team.

Ports・AMK SPC Disassembler

Most VIP5 songs are not ported for modern addmusic. A spc file you downloaded from youtube is not generated by AMK. This spc is from 'Real Hardware Compatible fix project VIP5.' It's just decreased echo delay value to 04 so that it can be played on the real hardware or accurate emulators. Therefore, you cannot use AMK Disassembler Tool to make this song compatible with AMK.

Well, I understand. However, this song, along with other songs from VIP Mario 5, were distributed by the Vipper Team on an uploader site, according to this video: https://www.youtube.com/watch?v=dfok2fpFz-0. The only thing they requested is to not distribute their songs in another sites. This means, in my opinion, that we are free to use their songs as long as we dont upload them to other site such as SMWCentral for example. If they distributed this song in their uploader site and was avalible for download for everyone, then we can use it without problems. Well, thats what I think.
Their uploader site is no longer available, so, when I found this SPC I wasnt expecting it to work, because AddMusicK 1.0.X SPC Disassembler says that only unmodified versions of AddMusicK 1.0.0 ~ 1.0.9 SPC is guaranteed to be supported. I decided to try to use the tool with the SPC and I was surprised when it worked. I tested the song with AddMusicK and at first the song was fine, until I heard that channels 5, 6 and 7 were detuned. Also, normally, sampled songs from VIP Mario 5 make use of bnk for ther samples (for example, Super Mario Bros NES songs make use of a bnk file named ath_fami.bnk. This means that they are made for AddMusic 4 and thus their SPC files are incompatible with AddMusicK 1.0.X SPC Disassembler.
I think that the detuning can be fixed by changing a value at the $DE command, which handles vibrato. On channels 5, 6 and 7, the value is the same: $DE $18 $0C $40. I think that they are the same because they play the same note. So, maybe, by changing one or more of the values the song can be fixed, however, I dont know how to get the correct values. Or maybe Im wrong and the cause of detuning is other.

In summary: This song was distributed on the VIP Mario uploader site, so we have permission to use it. Also, since
AddMusicK 1.0.X SPC Disassembler worked with the SPC, it was generated by AddMusicK. By taking in consideration what I said before, any help for fixing the song would be appreciated.

Uploading the SPCs so people can listen to tracks from the hacks is not the same as providing the source files (i.e. the .txt and samples) for those same tracks so other people can reuse them. Disassembling those SPCs and trying to redistribute them would indeed fall under C6. I don't think people will be inclined to help fix this given it's known the VIP team didn't want people to reuse the ports.

Well, as I said before, the song was actually distributed on the VIP Mario uploader site. Not only this song, also, the resource pack was distributed as well. The song was distributed with the txt file and samples (bnk). However, now the VIP Mario 5 uploader site is down, this means that the song is no longer avalible for download. But at some moment everyone could download this song and the resource pack. While I found the resource pack, it didnt include some of the songs, for example, the song I was requesting help to fix.
Also, the description of the previous video: https://www.youtube.com/watch?v=dfok2fpFz-0 says: ∞たのしいおいかけっこ∞
From VIP 5.
Found on the now deceased Japanese uploader site. Author unknown.
(This means the download for the song is gone from the internet).
This means that at some moment, the song was avalible for everyone. If Vipper team doesnt want people to reuse the port (or the resource pack), why they would distribute it in their uploader site, with an avalible download for everyone?. Also, returning to the point of the SPC, there is a big difference between the SPC distributed with the VIP 5 Music pack (the SPCs, without any txt or bnk files) and the SPC from this video: https://www.youtube.com/watch?v=4CxX3BSg84A. The first one cannot be played properly on an acurrate SPC player, it only plays the first note, also it doesnt work with AddMusicK 1.0.X SPC Disassembler. The second one, the one from the video, plays fine and it works with AddMusicK 1.0.X SPC Disassembler. This is the reason why I think that the author of the video has the txt and bnk files from the song (probably he downloaded them when the download of the txt and samples was still avalible at the VIP Mario uploader site) but he doesnt want to share them, in respect to the Vipper team of not redistributing their songs in other sites.

In conclusion, Im a bit confused, because, at this point, I dont know if the fact that this song was avalible previously for download means that we have permission to use it. Because I dont want to violate any rule, the only thing I was trying to do is to recover a song that is no longer avalible for download and try to use it in my hack. Because I think that if it was distributed previously and everyone could download the song, with the original txt and bnk samples (but not redistribute it), then that means that Vipper team wanted others to use the song, because if they wanted to make the song exclusive for VIP Mario 5, they wouldnt distribute the txt and samples for using the song.

Because they put files on some public file uploading sites does NOT mean they expect any outsiders to use these files. Back then, when VIP Mario was created, there were no easy and convenient ways for transfering and sharing files between hobby team members over the internet, and Discord didn't exist until 2015. A public uploader site would be an easy option for people who were collaborating in forums. And they never explicitly released these resources other than uploading to the site without an formal announcement or submission.

As of now, if you see their wiki site, you can see it's still maintained as of now, and the site only providing SPCs for VIP Mario 3, 4 and 5. If they really had the intent of releasing their resources, they would have put them in the site.

Finally, you can download files from somewhere does NOT mean you got the right to use these stuff (at least in most countries, this is how copyright law works). A port from other game can be considered as derivative work, and the author of such derivative work does hold their part of copyright.

My suggestion is just don't use this song at all (or any stuff with unclear licensing). You may try to look through our custom music section, which has huge catalog for different use cases inside a SMW hack.
