Use Audacity, anything above 22050khz should sound similar, but remember, almost any converter will stumble downhill from there.

The WAVs MUST be 8-bit usigned, mono and should not exceed 22KHz. I use Cool Edit Pro 2 for all my audio editing needs...

BTW, this ROM does not work on real HW, on the Sega logo, it will do some illegal read/write in some part of the machine and it will lock up, and reset won't help.

EDIT: Also, how friggin' tiny does the WAV have to be? I've got the one I want down from 18.3MB to 61KB, and still can't get a rom to compile in S1

How the heck did you make it so small?! o_O

[TmEE]

you can use MP3, OGG, WMA, ADPCM etc compression in WAV if you want....

[Sik]

But doesn't the driver only take raw waveforms?

[TmEE]

That's the reason the guy with problem didn't get any good sound the driver assumes all data it is fed with is what is needed and when the data is different, you usually hear very non pleasing sounds :P

I wasn't using 8-bit, which Is why I was having the problem. Thanks TmEE.

How is the quality of the sound? I don't know if the specific instructions I gave about improving quality by commenting those Z80 stops will work in Sonic 2.

TmEE: Maybe this has something to do with me not stopping the Z80 at JoypadInit?
Either that, or the now-corrupted SEGA sound is screwing up the Genesis (works fine in Fusion though).

This is a longshot at best but, if you're doing a move.l or move.w to Z80 RAM at some point, you may have to change that to move.b.

EDIT: Crappy. I also used the driver and same WAV in S1, S1's sounds better.

There's too little to be heard to judge quality of the sound.... it sounds good in Fusion, and Fusion is closest you get to real HW when it comes to sound.
Also, NONE of my stuff ever stops Z80 when controllers are accessed, so far I've not had ANY problems on any of my Sega systems (MD1, 2xMD2, 2xNomad)... Sega however does strongly advise you to stop Z80 on controller access... I see no reason why...

The corrupt Sega sound is definitely the cause for the lock-up.... emulators don't emulate lock-ups when you read/write to areas in MD outside ROM, RAM, VDP and I/O area. Comment out the Sega sound code and I'll give it another shot.

Just a lil' error fix I worked out; I kept getting a "bad size on opcode beq.l playmusic81" message when I tried building the S1.rom back together. If anyone else is having the same problem, change the code:

cmpi.b #$81,d7
beq.l PlayMusic81

to this one:

cmpi.b #$81,d7
beq.s PlayMusic81

in other words, replace the "beq.l" with "beq.s" instead. =P

In regen.ini set "EmulateLockups=1" . And btw, sound should be as accurate as real hardware in the latest Regen beta 3.

stay safe,

This is an amazing accomplishment! Great job with this, I'm amazed how good it sounds. The music doesn't play in Gerbil's Gens, but works fine in Generator. The bass is so good I cranked it up on my stereo
