Sonic Anniversary Celebrations thread

23 June 2011 - 12:06 AM

Twenty years ago, on June 23, 1991, Sonic the Hedgehog 1 was released on the Genesis, and it marked the beginning of one of my favorite franchises as a kid (I still love Sonic to this day, by the way). Happy 20th Birthday, Sonic! Let's hope this year will be your best!

What are you going to do for Sonic's birthday today? I know what I'm doing, I'm going to do some online races in Sonic & Sega All-Stars Racing, as well as replaying through levels in Sonic Colors, as I am trying to get a couple of S Ranks in the game myself.

How to seperate Super Sonic's mappings from Sonic's mappings

08 June 2010 - 02:11 PM

As you can see in Stealth's Sonic and Knuckles disassembly, Sonic's mappings and PLCs have been seperated from Super Sonic's mappings and PLCs, while Sonic 2 has Super Sonic and Sonic's PLCs and mappings together in two different files, a mappings file, and a PLC file.

To seperate Super Sonic's mappings/PLCs with Sonic's mappings/PLCs, do the following steps as described here:

First, go to "Sonic_Super:"

Syntax Highlighted Code: ASM

Sonic_Super:
	tst.b	(Super_Sonic_flag).w	; Ignore all this code if not Super Sonic
	beq.w	return_1AC3C
	tst.b	(Update_HUD_timer).w
	beq.s	Sonic_RevertToNormal ; ?
	subq.w	#1,(Super_Sonic_frame_count).w
	bpl.w	return_1AC3C
	move.w	#60,(Super_Sonic_frame_count).w	; Reset frame counter to 60
	tst.w	(Ring_count).w
	beq.s	Sonic_RevertToNormal
	ori.b	#1,(Update_HUD_rings).w
	cmpi.w	#1,(Ring_count).w
	beq.s	+
	cmpi.w	#10,(Ring_count).w
	beq.s	+
	cmpi.w	#100,(Ring_count).w
	bne.s	++
+
	ori.b	#$80,(Update_HUD_rings).w
+
	subq.w	#1,(Ring_count).w
	bne.s	return_1AC3C

Replace it with this:

Syntax Highlighted Code: ASM

Sonic_Super:
	tst.b	(Super_Sonic_flag).w	; Ignore all this code if not Super Sonic
	beq.w	return_1AC3C
	tst.b	(Update_HUD_timer).w
	beq.s	Sonic_RevertToNormal ; ?
	tst.b	(Super_Sonic_flag).w; switch on the super sonic flag
	move.l	#Mapunc_SuperSonic,mappings(a0)	; load Super Sonic's art
	bra.w	ContSonic_Super		; branch to rest of code
ContSonic_Super:
	subq.w	#1,(Super_Sonic_frame_count).w
	bpl.w	return_1AC3C
	move.w	#60,(Super_Sonic_frame_count).w	; Reset frame counter to 60
	tst.w	(Ring_count).w
	beq.s	Sonic_RevertToNormal
	ori.b	#1,(Update_HUD_rings).w
	cmpi.w	#1,(Ring_count).w
	beq.s	+
	cmpi.w	#10,(Ring_count).w
	beq.s	+
	cmpi.w	#100,(Ring_count).w
	bne.s	++
+
	ori.b	#$80,(Update_HUD_rings).w
+
	subq.w	#1,(Ring_count).w
	bne.s	return_1AC3C

This will make sure if Super Sonic will run his own mappings and animation script instead of using Sonic's mappings with a different animation script.

Then, go to "loc_41C56:"

Syntax Highlighted Code: ASM

loc_41C56:
	btst	#4,(Ctrl_1_Press).w
	beq.s	return_41CB6
	moveq	#0,d0
	move.w	d0,(Debug_placement_mode).w
	lea	(MainCharacter).w,a1 ; a1=character
	move.l	#Mapunc_Sonic,mappings(a1)
	move.w	#$780,art_tile(a1)
	tst.w	(Two_player_mode).w
	beq.s	loc_41C82
	move.w	#$3C0,art_tile(a1)

Then replace it with this:

Syntax Highlighted Code: ASM

loc_41C56:
	btst	#4,(Ctrl_1_Press).w
	beq.s	return_41CB6
	moveq	#0,d0
	move.w	d0,(Debug_placement_mode).w
	lea	(MainCharacter).w,a1 ; a1=character
	tst.b	(Super_Sonic_flag).w
	bne.w  SuperSonicDebugMappings
	move.l	#Mapunc_Sonic,mappings(a1)
	move.w	#$780,art_tile(a1)
	tst.w	(Two_player_mode).w
	beq.s	loc_41C82
	move.w	#$3C0,art_tile(a1)
 
SuperSonicDebugMappings:
	move.l	#Mapunc_SuperSonic,mappings(a1)
	move.w	#$780,art_tile(a1)
	tst.w	(Two_player_mode).w
	beq.s	loc_41C82
	move.w	#$3C0,art_tile(a1)

This will make sure that whenever you are either Sonic or Super Sonic using the game's debug mode by pressing the B button to enter object placement mode, then pressing the button again whenever you are either Sonic or Super Sonic, either character's mappings will appear. Say if you are playing as Super Sonic, press B to enter object placement mode, press it again, then you will have Super Sonic mappings instead of Sonic's regular mappings.

Then, go to "LoadSonicDynPLC_Part2:"

Syntax Highlighted Code: ASM

LoadSonicDynPLC_Part2:
	cmp.b	($FFFFF766).w,d0
	beq.s	return_1B89A
	move.b	d0,($FFFFF766).w
	lea	(MapRUnc_Sonic).l,a2
	add.w	d0,d0
	adda.w	(a2,d0.w),a2
	move.w	(a2)+,d5
	subq.w	#1,d5
	bmi.s	return_1B89A
	move.w	#-$1000,d4

Change it to this:

Syntax Highlighted Code: ASM

LoadSonicDynPLC_Part2:
	cmp.b	($FFFFF766).w,d0
	beq.s	return_1B89A
	move.b	d0,($FFFFF766).w
	cmpi.b	#1,(Super_Sonic_flag).w; switch on the super sonic flag
	beq.s	SonicPLCLoad		; if not, load Sonic's art
	lea	(MapRUnc_Sonic).l,a2	; load Sonic's art
	bra.s	ContLoadPLC		; branch to rest of code
SonicPLCLoad:
	cmpi.b	#0,(Super_Sonic_flag).w; switch off the super sonic flag
	beq.s	SonicPLCLoad2		; if not, load Sonic's art
	lea	(MapRUnc_SuperSonic).l,a2 ; load Super Sonic's art
	bra.s	ContLoadPLC		; branch to rest of code
SonicPLCLoad2:
	lea	(MapRUnc_Sonic).l,a2
ContLoadPLC:
	add.w	d0,d0
	adda.w	(a2,d0.w),a2
	move.w	(a2)+,d5
	subq.w	#1,d5
	bmi.s	return_1B89A
	move.w	#-$1000,d4

This will make sure that Super Sonic will have his own PLCs whenever the player is playing as Super Sonic.

Then, add this line under "Mapunc_Sonic:"

Syntax Highlighted Code: ASM

;--------------------------------------------------------------------------------------
; Sprite Mappings
; Super Sonic			; MapUnc_6FBE0: SprTbl_Sonic:
;--------------------------------------------------------------------------------------
Mapunc_SuperSonic:	BINCLUDE	"mappings/sprite/Super Sonic.bin"

Add this one under "MapRUnc_Sonic:"

Syntax Highlighted Code: ASM

;--------------------------------------------------------------------------------------
; Sprite Dynamic Pattern Reloading
; Super Sonic DPLCs   		; MapRUnc_714E0:
;--------------------------------------------------------------------------------------
; WARNING: the build script needs editing if you rename this label
;          or if you move Sonic's running frame to somewhere else than frame $2D
MapRUnc_SuperSonic:	BINCLUDE	"mappings/spriteDPLC/Super Sonic.bin"

These files will make sure that Super Sonic does indeed, have his own mappings and PLCs.

Next, go to "SAnim_WalkRun:" and take a look at this line:

Syntax Highlighted Code: ASM

	tst.b	(Super_Sonic_flag).w
	bne.s	SAnim_Super
	lea	(SonAni_Run).l,a1	; use running animation
	cmpi.w	#$600,d2		; is Sonic at running speed?
	bcc.s	+			; use running animation
	lea	(SonAni_Walk).l,a1	; if yes, branch
	add.b	d0,d0

Remove the following lines:

Syntax Highlighted Code: ASM

	tst.b	(Super_Sonic_flag).w
	bne.s	SAnim_Super

They need to be removed because they will load the corkscrew animations with Super Sonic's walking/running sprites.

Lastly, you can now copy and paste Sonic's animations for Walking, Running, and Pushing from Sonic's anmation script:

Syntax Highlighted Code: ASM

; ---------------------------------------------------------------------------

	even

This method will let Super Sonic use Sonic's regular walking, running, pushing, standing/wait, balancing and ducking sprite mappings and PLCs instead of using his own.

And here are the files:

http://www.fileden.com/files/2007/2/10/758...appingsPLCs.rar

Note: The sprites used in the mappings are the same as the regular Sonic 2 Super Sonic sprites.

That's all for now, I will cover how to seperate his sprites from Sonic's sprites soon.

How to Expand the music index to start at $00 instead of $80

03 January 2010 - 08:23 PM

Well, since Tweaker released the Sonic 2 Clone Driver, I might as well post this guide that I had to keep private since May 26, 2009.

NOTE: First off, Credit HPZMan for the Original Guide he made for Sonic 1, which can be found at SCHG:How-to:Expand the music index to start at $00 instead of $80

Second of all, you need to have the Sonic 2 Clone Driver in your hack, to get the Clone Driver, go to this topic, this requires the Sonic 1 Sound Driver to be installed in your Sonic 2 hack first.

First, go to "PlayMusic:"

You will see something like this:

Syntax Highlighted Code: ASM

 
PlayMusic:
;	tst.b	($FFFFFFE0).w
;	bne.s	+
;	move.b	d0,($FFFFFFE0).w
	move.b	d0,($FFFFF00A).w
	rts
+
	move.b	d0,($FFFFF00A).w
	rts

Change it to:

Syntax Highlighted Code: ASM

 
PlayMusic:
        cmpi.b #$7F, d0
        ble.s   ChkSounds00to7F
        jmp     NormalSoundRequest
ChkSounds00to7F:
        cmpi.b #$01, d0
        bge.s   LoadSlots00to7F
        jmp     NormalSoundRequest
LoadSlots00to7F:
        add.b   #$80, d0; Add $80 you get slot that starts in $81            
        move.b #$01, ($FFFFFFFC) .w; $FFFFFC moves $01 you you make sound to driver load secound index
NormalSoundRequest:
        move.b    d0, ($FFFFF00A) .w
        rts

Then, go to "PlaySound:".

You will see something like this:

Syntax Highlighted Code: ASM

 
PlaySound:
	move.b	d0,($FFFFF00B).w
	rts

Change it to:

Syntax Highlighted Code: ASM

 
PlaySound:

ChkSounds00to7F_Special:
        cmpi.b #$01, d0
        bge.s   LoadSlots00to7F_Special
        jmp     NormalSoundRequest_Special
LoadSlots00to7F_Special:
        add.b   #$80, d0; Add $80 you get slot that starts in $81            
        move.b #$01, ($FFFFFFFC) .w; $FFFFFC moves $01 you you make sound to driver load secound index
NormalSoundRequest_Special:
        move.b    d0, ($FFFFF00B) .w
        rts

Then, go to "loc_7202C:"

You will see something like this:

Syntax Highlighted Code: ASM

 
loc_7202C:
		jsr	sub_725CA(pc)
		movea.l	(off_719A0).l,a4
		subi.b	#$81,d7
		move.b	(a4,d7.w),$29(a6)
		movea.l	(Go_MusicIndex).l,a4

Change it to:

Syntax Highlighted Code: ASM

 
loc_7202C:
        	jsr    sub_725CA (PC)
        	movea.l    (off_719A0) .l, a4
        	subi.b    #$81, d7
        	move.b    (a4, d7.w), $29 (a6)
        	movea.l    (Go_MusicIndex) .l, a4
        	cmpi.b #$01, ($FFFFFFFC) .w
        	bne.s   NormalIndexLoad
        	movea.l    (Go_MusicIndex_01to1F) .l, a4
NormalIndexLoad:
        	clr.w   ($FFFFFFFC) .w

Then, search for "Go_MusicIndex:"

You will see something like this:

Syntax Highlighted Code: ASM

 
Go_MusicIndex:	dc.l MusicIndex		; XREF: Sound_81to9F

Add this below "Go_MusicIndex:":

Syntax Highlighted Code: ASM

 
Go_MusicIndex_01to1F:	dc.l MusicIndex_01plus

Then, go to "MusicIndex:"

You will see something like this:

Syntax Highlighted Code: ASM

 
MusicIndex:	dc.l Music81, Music82
		dc.l Music83, Music84
		dc.l Music85, Music86
		dc.l Music87, Music88

		dc.l Music97, Music98
		dc.l Music99, Music9A
		dc.l Music9B, Music9C
		dc.l Music9D, Music9E
		dc.l Music9F

Then, add this below "MusicIndex:"

Syntax Highlighted Code: ASM

 
MusicIndex_01plus:
         	dc.l Music01, Music02

The "dc.l Music01, Music02" is basically an example of what music slots you should use for Slots $01 to any number you want to stop at

Then, go to "Sound_ChkValue:"

You should see something like this:

Syntax Highlighted Code: ASM

 
Sound_ChkValue:				; XREF: sub_71B4C

		cmpi.b	#$F0,d7
		ble.w	Sound_A0ToCF
		cmpi.b	#$F9,d7
		bge.w	Sound_E0toE4

Change it to:

Syntax Highlighted Code: ASM

 
Sound_ChkValue:            ; XREF: sub_71B4C
        	moveq    #0, d7

		cmpi.b	#$F0,d7
		ble.w	Sound_A0ToCF

		bge.w	Sound_E0toE4

Now, go to "Sound_81to9F:", and change it to this:

Syntax Highlighted Code: ASM

 
Sound_ChkValueFor00:
        	cmpi.b #$FF, d7; $FF = Last slot will be musics in index $00 - $7F ($FF = $7F)

		cmpi.b	#$98,d7		; is "extra life" music	played?
		bne.s	loc_72024	; if not, branch
		tst.b	$27(a6)
		bne.w	loc_721B6
		lea	$40(a6),a5
		moveq	#9,d0

Finally, we are going to Change the number of sound test slots in the options menu

Go to "word_917A:"

You will see something like this:

Syntax Highlighted Code: ASM

 
	dc.w $7FFF	; 4
	dc.w Sound_test_sound	; 5

Change the "$7" in "$7FFF" to anything you like, like "$FFFF", or "$CFFF"

That's all for now, I will cover Level Select Sound Test Slot expansion soon.

Mikel's Unnamed Sonic 3K hack

25 October 2009 - 07:28 PM

Well, many of you know that I am working on a Sonic 2 hack named Sonic Zeta Overdrive, but I am also working on a hack of Sonic 3K, so far, I have changed the palettes for a couple of the zones, I will also include Layout and Special Stage edits, and when Varion releases his Sonic 3K split disassembly in the future, I will do ASM edits, like adding the Jump Dash and Light Dash, and adding the Sonic 1 Sound Driver to Sonic 3K.

Here are some screenshots:

Mushroom Hill Zone at Day (Act 1):

Mushroom Hill Zone at Evening (Act 2):

These are all the screenshots I can offer, more screenshots are coming soon, Comments, Name suggestions, and Criticism are welcome.

How to add Dynamic Palettes in Sonic 2 SMS

22 February 2009 - 08:48 PM

I would like to thank Glitch for both, the Sonic 2 SMS disassembly, and the program Aspect Edit.

Ok, if you have been playing Sonic 2 SMS in the past, you may notice that four zones in the game lack the use of Dynamic Palettes, as only three of the zones in the original game use them. The four zones that lacked Dynamic Palettes were:

Underground Zone, Green Hills Zone, Gimmick Mountain Zone and Scrambled Egg Zone.

So, if you want to add Dynamic Palettes for those four zones in Sonic 2 SMS, follow these instrcutions below:

First, go to LevelPaletteValues in the Sonic 2 SMS disassembly, located in src/s2.asm, and you will get something like this:

Syntax Highlighted Code: ASM

Take a look at Underground Zone for example:

Syntax Highlighted Code: ASM

.[color= #00CC66;]db[/color] [color= #ff0000;]$[/color][color= #ff0000;]0E[/color], [color= #ff0000;]$[/color][color= #ff0000;][color= #ff0000;]09[/color][/color]

.[color= #00CC66;]db[/color] [color= #ff0000;]$[/color][color= #ff0000;]0E[/color], [color= #ff0000;]$[/color][color= #ff0000;][color= #ff0000;]09[/color][/color]

.[color= #00CC66;]db[/color] [color= #ff0000;]$[/color][color= #ff0000;]0E[/color], [color= #ff0000;]$[/color][color= #ff0000;][color= #ff0000;]09[/color][/color]

As you can see, $0E is the zone palette for Underground Zone, and $09 is the palette for Sonic in Underground Zone.

Then, Open up Aspect Edit, and click on the Open Palette button:

Right now, we are going to edit Underground Zone's palette, so click on "palette_ugz.bin" (Which is located in the palettes folder) in the file browser:

Then, you can edit the colors in the palette, after you're done, click the Save Palette as button:
Posted Image

When it asks for a new filename, save it as "palette_ugz2.bin" for Act 2, and "palette_ugz3.bin" for Act 3.

For GHZ, do the same method, but open "palette_ghz.bin", and save it as "palette_ghz2.bin" for Act 2, and "palette_ghz3.bin" for Act 3.

Same goes for SEZ, and GMZ. open "palette_sez.bin" for SEZ, and "palette_gmz.bin" for GMZ, for SEZ, save it as "palette_sez2.bin" for Act 2, and "palette_sez3.bin" for Act 3. And for GMZ, save it as "palette_gmz2.bin" for Act 2, and "palette_gmz3.bin" for Act 3.

Then, If you want Underground to go through a Day-to-Night, do this:

Syntax Highlighted Code: ASM

.[color= #00CC66;]db[/color] [color= #ff0000;]$[/color][color= #ff0000;]0E[/color], [color= #ff0000;]$[/color][color= #ff0000;][color= #ff0000;]09[/color][/color]

And for Green Hills Zone to Scrambled Egg, do this:

Syntax Highlighted Code: ASM

[color= #adadad; font-style: italic;];ghz[/color]

.[color= #00CC66;]db[/color] [color= #ff0000;]$[/color][color= #ff0000;][color= #ff0000;]13[/color][/color], [color= #ff0000;]$[/color][color= #ff0000;][color= #ff0000;]04[/color][/color]

[color= #adadad; font-style: italic;];sez[/color]

.[color= #00CC66;]db[/color] [color= #ff0000;]$[/color][color= #ff0000;][color= #ff0000;]15[/color][/color], [color= #ff0000;]$[/color][color= #ff0000;]0B[/color]

And lastly, add these lines at the end of src/includes/palettes.asm:

Syntax Highlighted Code: ASM

Palette_UGZ_2:    [color= #adadad; font-style: italic;];$2F[/color]

.[color= #00bfff;]incbin[/color] [color= #CC33CC;]"palettespalette_ugz2.bin"[/color]
