So one day, about a year ago, I decided to try to port flamewing's S3K Sound driver into Sonic 2. I had originally planned to release this quite a while ago, but have been real busy with real life.
This guide was written with the HG version of the Sonic 2 disassembly in mind, however, it should work with the old and ancient Xenowhirl disassembly as well. For HG users, this guide will fix the sound effects/music so it uses all Sonic 2 sound effects and music. Unfortunately, for Xeno users, you will have to manually go through and fix all the sound/music ids by hand. Anyway, on to the guide:
That about wraps that up. I would like to thank flamewing for his awesome s3k driver and his very cool tool! Go here to see what his driver and tool is about.

PREPARING FOR THE SOUND DRIVER
1. Go to - VintSub0: and delete these three lines
You should have something that looks like this:
2. Ok, Next got to the following labels:
• loc_54A:
• Vint0_noWater:
• loc_748:
• VintSub18:
• VintSub16:
• loc_EFE:
And delete this line:
3. Similarly, go to these labels as well
• Vint10_specialStage:
• loc_BD6:
and delete this line:
4. Go to
Once there, scroll down just a little and you will see:
Delete that as well.
UPGRADING THE LOAD DRIVER ROUTINE
1. Go to
and delete all the code right before JmpTo_LoadTilesAsYouMove:
Under that is:
Delete all of it up to:
But make sure that you leave this line or you will get an error:
2. OK, let's start adding the S3K driver!!!!!
Go to:
Delete these:
and ADD the following:
Upgrading the Playback Routines
1. Find
and replace it's code with the following:
2. Next, is a little different. Delete all of:
Replace it with:
Upgrading Pause / Resume routines
1. So, starting from where we left off, PauseGame should be right under the PlayMusic/PlaySound routines. First thing we need to do, is fix a future error. So, from PauseGame, scroll down until you see this:
That should be the 9th line from PauseGame. Let's edit it to this:
2. Continue scrolling until you find:
Delete it, and replace it with these three lines:
3. To resume music, Go to:
And delete this:
Replace it with:
4. And to fix the Slow motion pause/unpause, Go to:
And delete:
Replace it with:
5. Next, fixing the speed shoes! Go to:
Delete these:
Next, go to:
Delete these two lines:
and replace them with this:
Same thing as before, but with Tails. Find this:
(*note: that line is commented out.)
Replace these lines:
with these:
Replacing S2 driver with new S3K driver
1. Go to:
and delete the inner contents. It should look like this when you are done:
2. After that, delete everything after that label, upto but not including
3. Find
Now, right above
4. Download flamewing's sound diver:
http://www.mediafire...songs-sfx-v3.7z
Now open the compressed file and copy everything to the sound folder.
in the sound folder, delete "Z80 Sound Driver.asm" file.
5. Now Download this:
https://www.dropbox....sounddriver.asm
and replace s2.sounddriver.asm in your Sonic hack folder with the one of the same name that you downloaded.
6. download this package:
https://www.dropbox....21rtc/win32.rar
and replace win32 folder with it.
7. Last, download https://www.dropbox..../Sega%20PCM.bin
and put it in you "sound" folder.
FIXING CONSTANTS AND MUSIC/SOUND POINTERS
1. Open s2.constnts.asm
2. Change
3. Find
Here is what the area we are going to change looks like now:
Go ahead and delete it and replace it with the following:
4. We are going to do the same for the sound effects. right after the music pointers, you should see the following:
Delete it and replace it with this
FIXING SOUND TEST
1. Fixing the sound test in the options menu is very easy. First, go to
Delete it.
2. Right under that find
It should look like this
We want to edit that last line. Change the ($80-1) to $FF. So it should look like:
3. To fix the Level Select Sound test, go to
find this section of code:
Remove the last two lines. It should now look like this:
Under that, is this:
Delete the last three lines. It should now look like this:
Right under that section of code you should see:
As before, delete the last line. Should look like this:
And last, the final part of the code, look for
And delete it!
The whole routine should look like this: (I commented my lines out)
Now build and enjoy!
PREPARING FOR THE SOUND DRIVER
1. Go to - VintSub0: and delete these three lines
stopZ80 ; stop the Z80 bsr.w sndDriverInput ; give input to the sound driver startZ80
You should have something that looks like this:
VintSub0: cmpi.b #GameModeID_TitleCard|GameModeID_Demo,(Game_Mode).w ; pre-level Demo Mode? beq.s loc_4C4 cmpi.b #GameModeID_TitleCard|GameModeID_Level,(Game_Mode).w ; pre-level Zone play mode? beq.s loc_4C4 cmpi.b #GameModeID_Demo,(Game_Mode).w ; Demo Mode? beq.s loc_4C4 cmpi.b #GameModeID_Level,(Game_Mode).w ; Zone play mode? beq.s loc_4C4 ; stopZ80 ; S3K ; stop the Z80 ; S3K ; bsr.w sndDriverInput ; S3K ; give input to the sound driver ; startZ80 ; S3K ; start the Z80 bra.s VintRet ; ---------------------------------------------------------------------------
2. Ok, Next got to the following labels:

2. OK, let's start adding the S3K driver!!!!!
Go to:
JmpTo_SoundDriverLoad:
Delete these:
nop jmp (SoundDriverLoad).l
and ADD the following:

FIXING SOUND TEST
1. Fixing the sound test in the options menu is very easy. First, go to
OptionScreen_Controls:and find this line:
addi.w #$80,d0
Delete it.
2. Right under that find
OptionScreen_Choices:
It should look like this
; word_917A: OptionScreen_Choices: dc.l (3-1)<<24|(Player_option&$FFFFFF) dc.l (2-1)<<24|(Two_player_items&$FFFFFF) dc.l ($80-1)<<24|(Sound_test_sound&$FFFFFF)
We want to edit that last line. Change the ($80-1) to $FF. So it should look like:
; word_917A: OptionScreen_Choices: dc.l (3-1)<<24|(Player_option&$FFFFFF) dc.l (2-1)<<24|(Two_player_items&$FFFFFF) dc.l $FF<<24|(Sound_test_sound&$FFFFFF)
3. To fix the Level Select Sound test, go to
LevSelControls_CheckLR:
find this section of code:
btst #button_left,d1 beq.s + subq.b #1,d0 bcc.s + moveq #$7F,d0
Remove the last two lines. It should now look like this:
btst #button_left,d1 beq.s + subq.b #1,d0
Under that, is this:
beq.s + addq.b #1,d0 cmpi.w #$80,d0 blo.s + moveq #0,d0
Delete the last three lines. It should now look like this:
beq.s + addq.b #1,d0
Right under that section of code you should see:
+ btst #button_A,d1 beq.s + addi.b #$10,d0 andi.b #$7F,d0
As before, delete the last line. Should look like this:
+ btst #button_A,d1 beq.s + addi.b #$10,d0
And last, the final part of the code, look for
addi.w #$80,d0
And delete it!
The whole routine should look like this: (I commented my lines out)
; loc_9522: LevSelControls_CheckLR: cmpi.w #$15,(Level_select_zone).w ; are we in the sound test? bne.s LevSelControls_SwitchSide ; no move.w (Sound_test_sound).w,d0 move.b (Ctrl_1_Press).w,d1 btst #button_left,d1 beq.s + subq.b #1,d0 ; bcc.s + ; moveq #$7F,d0 + btst #button_right,d1 beq.s + addq.b #1,d0 ; cmpi.w #$80,d0 ; blo.s + ; moveq #0,d0 + btst #button_A,d1 beq.s + addi.b #$10,d0 ; andi.b #$7F,d0 + move.w d0,(Sound_test_sound).w andi.w #button_B_mask|button_C_mask,d1 beq.s + ; rts move.w (Sound_test_sound).w,d0 ; addi.w #$80,d0 ; here bsr.w JmpTo_PlayMusic lea (debug_cheat).l,a0 lea (super_sonic_cheat).l,a2 lea (Night_mode_flag).w,a1 moveq #1,d2 ; flag to tell the routine to enable the Super Sonic cheat bsr.w CheckCheats + rts
Now build and enjoy!
That about wraps that up. I would like to thank flamewing for his awesome s3k driver and his very cool tool! Go here to see what his driver and tool is about.
