Wow, this is awesome and it's a pretty good sounding track too. 2013 is going out with a bang in the community-- all of you guys are kicking ass

Is there a .sgc file for Sonic 1?

There is but just for Sonic 1 GG :/

When I worked on smps2mid, I verified that the music data of the MS and GG versions matches exactly. (except for one additional command in the Good Ending "sound effect")

Therefore all the sound data from $FB27 onwards is not, as far as I can tell, part of a known track. However, it is missing a song header, and looks like a partial channel 3 and complete channel 4 of an unknown song.
I may, of course, be entirely wrong.

Is there anybody who would know how to re-piece this together and get this to play?

I tried to convert it with smps2mid and didn't get any useful results. I'm pretty sure that this is the data for sound effects though. (The first few notes looked like the ring sound effect and there are many special commands between notes.)

But how didn't Marble get caught in the SGC rip?

It even got an unused credits theme in Sonic 2 SMS o.o

[ValleyBell]

There is no reference to the song anywhere. You can not play something that you don't know it even exists.

If you look at the Sonic 2 SMS/GG song list on SMSPower (search for "Sonic the Hedgehog 2"), you'll notice that it lists the unused songs. But Sonic 1 SMS doesn't have Marble Zone in its list.
(Surprisingly there doesn't seem to be a music location list for Sonic 2 SMS on the Retro wiki, btw, even though there is one for Sonic Chaos and STT.)


Small note to the area with unknown sound data ($FB27-$FFB1): It's referenced by the SFX list at $C740.

ValleyBell, is there a format (VGM, MID) that the Sonic 1 music could be converted to, that one could reverse so as to get back the tune data in the ROM? I ask is because for my level editor I want to store the project data in easily viewable / accessible formats -- PAL for palettes, BMP for graphics, CSV for grid data, INI for text & metadata etc. -- so that for what my editor doesn't offer (for now), people can use external tools for. With music though, I don't know what format is reversable.

[Master Emerald]

Ah so it's the same case as the Boss in Sonic 3D.

I bet there's more unused Songs in the other 8 bit games. Or even in the 16bit games/protos, who knows?

There is no format that's directly and easily reversable.
Reversing .VGM is pretty much impossible, since it just logs what the sound driver writes to the sound chip. (almost like .wav files)
MIDIs are okay in general, but they lack support for loops and don't have direct support for all special commands. Reversing them is not impossible though, as mid2smps proves, but there are some limitations.
I would probably just save them as .bin files, that worked pretty well for SMPS music in the past years.

[Kroc]

I thougt as much. I wish to avoid copyright problems, but also for other reasons my editor will not ship with, nor store in the portable project files, any subsection of the ROM binary. For the music data I have imagined an ASM-like script specialised to the particular commands the S1 music data uses.

All I can do now is just wonder and picture what Marble Zone would have been like.

To be honest, I think it's a good thing that they decided to do unique levels in the end. That makes it age better, because if it had used the same layouts and zones as the MD counterpart, it would be worthless now, being just a lesser-spec version of the same game. The different zones help to keep it relevant, since it's something you can't get on the MD version. There's good reason to own both.

Very awesome find !

Not quite a .vgm rip, but it's certainly a VGM rip. Recorded from a real Mega Drive.

FLAC. Don't break my monthly bandwidth plzkthx.

Has this been ripped from an EU rom at 60hz, it sounds rapid.

Wow, this is really cool. Does the GG version have a stereo version of it?

I doubt it because the rest of the Soundtrack is mono and Valleybell already said the music data is the same between versions.

You know, 3 levels out of 6 are: Green Hill zone, Labyrinth zone and Scrap Brain zone. Half the game uses the same zones as the MD counterpart The Marble zone music is an awesome find, yet, not so surprising in the end.
