Esrael you're fucking awesome.

You win the internets.

Eduardo Knuckles · Aug 31, 2008

Just AWESOME.
But, you plan a proccedure to port the S3 driver to s1 too?

GasparXR · Aug 31, 2008

Next thing you know, someone will post a port of Sonic CD to the Sega Dreamcast. Wow.

Yuzu · Aug 31, 2008

If it's ported to Sonic 1, it'll be awesome.

Hitaxas · Aug 31, 2008

Now we need a detailed guide on how to port music to it. >.>

Master3k · Aug 31, 2008

:U

Great work, Esrael. Thanks for sharing that. Maybe I should try porting this to S2 sometime.

EDIT:To port music to S3, just do the opposite process from porting S3-S1.

Wow, lots of words so far.

This is pretty neat—and a nice technical achievement! But I prefer using 68k simply due to its vast potential for expansivity. Still, if you're looking for an established sound driver that gives you some extra cycles on the 68k, this should do the job nicely!

I do hope that everybody doesn't start using this driver because it's from Sonic 3, though! Consider what's involved in using this—changing all the sound effect calls in the game, manually managing the music pointers and where they compile in the ROM, keeping all your music within a $8000 byte boundary... there's a reason I prefer the 68k management system.

Working with Sonic 3's driver was an annoying pain for me; then again, I did it before we had stuff like the music pointer fixer, so who knows at this point? Maybe it's a good idea after all.

Irixion · Aug 31, 2008

Well I personally don't plan on using it, just seeing how it works. I've always wanted the s3 driver, and I guess now I have it =P

Hitaxas · Aug 31, 2008

I fixed up the driver to work with S2 final, but all I am getting is the sound effects. Any ideas?

RattleMan · Sep 1, 2008

Sonic 2 Delta 0.23, eh?

I like the boss hit counter.

Ayla · Sep 1, 2008

I always liked the s3 sound driver the best out of all of them. This is exciting news =)

Thanks, that worked.

Although, I experience some lag now...

Anyway, with all that said:
Here's the 2007 compatible version -> yay, a link to google!<-

Edit: there is some sort of slowdown in the game, caused by the driver, Esrael, do you think you could find the problem? =X

Hmmmm.... I get a "File not available" message.

Irixion · Sep 1, 2008

Hitaxas, like I said, it's somewhat related to the DAC, when a sample plays it lags.

Alriightyman, as soon as Hitaxas gets on I'll mirror it at Sonic Sanctuary.

Hitaxas · Sep 1, 2008

Link should work now, I just checked it.

As for what Irixion said, It seems like that would be the case... But I can't find what it is exactly.

EDIT: No, It doesn't work. D=

EDIT2: Mirror'd link

Irixion · Sep 1, 2008

Link doesn't work, just get rid of it.
