Discussion Section

Fails Hack Policy?

Are we still going to accept this? Because from the looks of things, this still doesn't do enough to comply to the Hack Policy. --BSonirachi (talk) 08:34, 7 June 2018 (CDT)

I don't know. Shadow05 01:08PM, 17 June 2018 (EST)

Opinions and Info

The next build is nearly complete, I still need to finish it but if you ask I'll release "V1.0B" Shadow05 01:25PM, 17 June 2018 (EST)

I've also released the builds from the Old and New Disassembly builds so here's all the versions (so far).

  • Version 0.5 (Genesis)
  • Version 0.5 (Mega CD)
  • Version 0.6 (Genesis)
  • Version 0.7 (Genesis and 32X)

Due to a bug the level select has been reverted back to Sonic 1's. Shadow05 12:14PM, 8 July 2018 (EST)


I'm trying to add the skid dust to Sonic 1 but it doesn't display can someone tell me why?


		move.b	#$D,$1C(a0)	; use "stopping" animation
		bclr	#0,$22(a0)
		move.w	#$A4,d0
		jsr	(PlaySound_Special).l ;	play stopping sound
		move.b	#6,($FFFFD1E4).w
		move.b	#$15,($FFFFD1DA).w

I fixed it here's how you do it, so goto loc_1DE20 and you'll see this.

		bra.s	loc_1DE28

loc_1DE20:				; DATA XREF: h+6E30?o
	        cmpi.b	#$C,$28(a2)
	        blo.s	loc_1DE3E

loc_1DE28:				; CODE XREF: h+6E42?j h+6E56?j ...

Delete the code before loc_1DE28.
