GF64's Custom SEGA screen modes

This should be compatible with both Sonic 1 and Sonic 2

• Add these variables at the start of your asm file...
  

Snd_Special_FadeOut equ $E0


Snd_Special_SEGA equ $E1


Snd_Special_StopSng equ $E4


RAM_SpriteAddr equ $FFFFD000 ;(Only used in SegaScreen) Change: $FFFFD000 for s1 or $FFFFB000 for s2


Game_Mode equ $FFFFF600 ;Delete this variable if you are using the S2 AS disasm


ModeID_Title equ $4


;Don't add these variables if you used the 6 button guide


RAM_Control_1_Press equ $FFFFF605


JoyStart equ $80

• Make a folder named "Modes"
  
• Download one of these custom SEGA screens:
  Classic
  Streets Of Rage
  
• Extract the "SegaScreen" folder in "Modes"
  
• Go to THE ORIGINAL "SegaScreen" label and delete everything until "TitleScreen:" (Sonic 1)
  

It should be like this:



; ---------------------------------------------------------------------------
; Sega screen


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


;SegaScreen: ; XREF: GameModeArray


include "Modes/SegaScreen/code.asm"


even



And that's all, simple


If you used the 6 button guide, in code.asm, replace:



cmp.b #JoyStart,(RAM_Control_1_Press).w



with



cmp.w #JoyStart,(RAM_Control_1_Press).w



By the way, don't forget to credit me.


EDIT 2: DON'T DELETE THE "GF64" WATERMARK (at the end of "code.asm") PLEASE.

 

I've already said this on IRC, but this is simply awesome. Do you mind if I put it up on Retro, with credits of course?


Hehe, I gots special stuff on mine


EDIT: I've put the SOR one into my hack yesterday already ^_^

 

(for those who are using SNASM68k)


just something that I did when I was putting this in, you should change this...



include "Modes/SegaScreen/code.asm"
even



to this...



include 'code.asm'
even



and also these three within code.asm...



ArtUnc_SegaLogoClassic:
incbin "Modes/SegaScreen/GFX.bin'


even


Pal_SegaLogoClassic:


incbin "Modes/SegaScreen/PAL.bin'


even


PalCyc_SegaLogoClassic:


incbin "Modes/SegaScreen/ANIPAL.bin'


even



to this...



ArtUnc_SegaLogoClassic:
incbin 'GFX.bin'


even


Pal_SegaLogoClassic:


incbin 'PAL.bin'


even


PalCyc_SegaLogoClassic:


incbin 'ANIPAL.bin'


even



that's how I got it working on my hack when I did this. other than that, looks awesome in the actual game itself. nice work ^_^

 

Got this working in Thrash (The SOR one, that is ^_^) - it's working great after a couple of fixes to make it work with AS. You should also consider removing the Game_Mode macro for the guide - the Xenowhirl dissasembly has this macro already.
