How to port some DAC samples of sonic 3 to sonic 1?

I need port some DAC samples to sonic 1. I tried to port the 3 files of dac of sonic 3 driver for esrael, and fail; and i dont know of samples offsets. How to can port?

 

Ok, here's what you need to do:


If you are editing the Sonic 1 Sound Driver through Puto's disassembly, you need to use something like this for porting Sonic 3 DAC samples:



dw DAC_Sample1 ; Kick sample
dw (DAC_Sample1_End-DAC_Sample1)


dw 0004h ; Pitch = 17h


dw 0000h


dw DAC_Sample2 ; Snare sample


dw (DAC_Sample2_End-DAC_Sample2)


dw 0004h ; Pitch = 1h


dw 0000h


dw DAC_Sample3 ; Timpani sample


dw (Dac_Sample3_End-DAC_Sample3)


Sample3_Pitch:


dw 000Bh ; Pitch = 1Bh


dw 0000h


DAC_Sample1: binclude "Samples/DAC1.bin"


DAC_Sample1_End:


DAC_Sample2: binclude "Samples/DAC2.bin"


DAC_Sample2_End:


DAC_Sample3: binclude "Samples/DAC3.bin"


DAC_Sample3_End:



If you are still getting errors, let me know.

 

Ok i have this disassembly but the sonic 3 driver, uses more samples in a single file. How to extract the samples?

 

I wrote a guide for this, but it's on Sonic Retro.

Ok but what is the s2' clone driver? The sound driver of sonic 2?

 

I use this.


Good luck...

 

..While I use this. =P


EDIT: With the additional routines I wrote to use more than 20 samples =P

 

Ok. To write MY samples i need to record in WAV?

 

That's nice.

You can do "WAV", or "raw."


I believe the format has to be 8-bit unsigned, mono, 11025Hz.


But you should try using these samples that Andlabs ripped from ROMs.

 

"From SonicRetro" Important to this topic I guess.


The samples as CarrascoZX0 said, must be a raw/wav pcm sample, 8-bit, mono, and either:


22,050Hz ($05 Pitch)


16,000Hz ($09 Pitch)


11,025Hz ($13 Pitch)


I think you could have the rates even smaller if you wanted to, but the quality loss wouldn't be worth it, most DAC drivers are operated using the Z-80 and are often read in banks, meaning that the samples cannot be too big (I'm asuming the size is "7FFF" bytes in total, though I haven't really checked if this can be twice the amount "FFFF"). However compressing the samples is also an important aspect which will change the size of the sample (Obviously), depending on what driver you use, for example, the driver CarrascoZX0 is using, requires that the samples must be compressed, using this compressor. If you're using the driver I am, then the samples are uncompressed so you do not need to worry about that.


There are pros and cons between using the compressed driver & the decompressed driver


Compressed Driver:


PROS: The size of tha samples are much shorter, so you could fit more samples on the rom without reaching your limit.


CONS: You have to compress a sample each time if you wanna use it, and there's a slight quality loss.


Decompressed Driver:


PROS: The quality of the sample is at it's fullest, and you do not need to worry about compressing it.


CONS: The size of the samples can be very big, and if you're careless enough to have too many useless samples, you'll end up taking up your rom space.

 

Ok. Actually are 3 samples of sonic 3 recorded in wav with pitch $13, mono and 8-bit unsigned and conpressed with jman'compressor decompressor. This is ok?

 

He can do only RAW. IF he uses the wave format, he will hear a unfortunate noise at the begin of the sample sound, because the wav files has a header inside, while the RAW are header-less.


Just for record, the S1HL driver is a FAKE-Z80 sound driver wich is written for prevent wasting of the 68k memory. Lots of unuseful 68k stuff there has been disabled, so the sample sound quality is considerable better than the Sonic 1's default. But not perfect as the uncompressed ones. For easy samples management I FULLY recommend the Sonic 2 Clone Driver because the S1HL driver works with aligned banks of samples, so your romfile will grew A LOT after using it AND you CANNOT add include or incbin after the samples, or your romfile will be larger than a 3,50MB file size.


In the Clone Driver you will get easy samples management, so I recommend it on your case. To obtain the S3 samples, you must get the s3 samples in wav format that is on the forums (I don't remember if they had been posted here on SSRG). But they are in the wav format, so you will need to remove the wav header from every sample file for get it being perfectly played on your hack.

 

*swoosh*

 

This is my final ask why i not speak good the english sorry. The sonic 2 clone driver is the driver of sonic 2? or is S1HL?

 

The Clone Driver is Sonic 1's sound driver with Sonic 2 music and sound effects.

 

Ok. Where is the download? (sorry for this stupid question)

Make sure you read the instructions carefully, you don't want issues with the thing.

 

Thanks

 

Hm, sorry for ask. But, this question has now been solved!?!?

I think that it seems to be a Yes.

 

Yes, Solved xD
