Sonic 2's spin dash dust object is also used for the splash when Sonic enters and exits water, and the dust that loads when he skids. If you have added that object to your hack, most likely by using part 2 of SonicRetro's spin dash guide, then the code for these features is already in your hack, and you just have to set the proper routines. This is what you do: Splash In Obj01_InWater and Obj01_OutWater, underneath "beq.s locret_12D80", replace the following line: Code: move.b #8,($FFFFD300).w ; load splash object with Code: move.w #$100,($FFFFD1DC).w ; set the spin dash dust animation to splash Skid Dust In loc_130BA and loc_13120, underneath "jsr (PlaySound_Special).l", add the following lines: Code: move.b #6,($FFFFD1E4).w ; set the spin dash dust routine to skid dust move.b #$15,($FFFFD1DA).w
The Skid Dust isn't showing up. I'm using the Github version not the Hivebrain one. Plus, there's no Sonic Retro Github Spindash Parts 2 and 3 guides, just the Hivebrain ones. Will they get added?
I'm saying this half of a year late, though, for anyone who's interested, you can find the GitHub equivalents in Sonic Water.asm and Sonic Move.asm.
