I'm working on my Sonic1 hack in a dissasbaly and I have noticed other people have ported spin dash to Sonic1. Unlike the others I only want to port the build up speed like Super Peel out in SonicCD. Instead of using a new sprite animation I only want to use his running animation when charging the dash. After releasing the A button I want to have him run forward, not roll. If anyone could tell me what code I need to bring over to Sonic 1 and where to place it I would apprecate it greatly.

You could make your own.

I would but I'm new to ASM and I don't know any ASM really. That's why I was gonna port part of the Spindash code.

Just the charge? Okay, lemme extract this right and quick...

Player_Charge_Spindash:

  move.b	($FFFFF602).w,d0
  btst	#1,d0
  bne.w	Player_Release_Spindash
  move.b	#$E,$16(a0)
  move.b	#7,$17(a0)
  move.b	#2,$1C(a0)
  addq.w	#5,$C(a0)
  move.b	#0,$39(a0)
  moveq	#0,d0
  move.b	$3A(a0),d0
  add.w	d0,d0
  move.w	Normal_Spindash_Speeds(pc,d0.w),$14(a0)
  tst.b	($FFFFFE19).w
  beq.s	loc_31675C
  move.w	Super_Spindash_Speeds(pc,d0.w),$14(a0)

Normal_Spindash_Speeds:
  dc.w  $800
  dc.w  $880
  dc.w  $900
  dc.w  $980
  dc.w  $A00
  dc.w  $A80
  dc.w  $B00
  dc.w  $B80
  dc.w  $C00
Super_Spindash_Speeds:
  dc.w  $B00
  dc.w  $B80
  dc.w  $C00
  dc.w  $C80
  dc.w  $D00
  dc.w  $D80
  dc.w  $E00
  dc.w  $E80
  dc.w  $F00

That should start you off. Credits to Stealth for the ported code (though to be honest I'm not sure how much of this particular code is changed).

Thanks for the help Tweaker, I'm gonna start work on putting it into the game soon.

I've noticed in some hacks such as Drx's Tails in Sonic 1, that the you go too fast and fly off screen. It doesn't result in death, but it won't refocus until you stop. Was this also happening in Sonic Jam?

To be honest, I never considered that as a bug. I thought it was cool and just left it as it was :P
