[QUOTE="Mildanner, post: 6624, member: 7577"] In the original game, the developers have made something in mind to make Sonic speed higher. And decided to make the flag to accelerate the music, when the speed shoes is over. It also slow down the music, with no Speed Shoes jingle. In this guide, you will go simply on the [B]_incobj/01 Sonic.asm[/B] (In older disassemblies, it was part of [B]Sonic Display.asm[/B]) and find these lines [CODE] move.w #bgm_Slowdown,d0 ; resume music... jmp (QueueSound1).l ; ...at normal speed[/CODE] Replace it with this (Code taken from invincibility) [CODE] moveq #0,d0 ; clear d0 move.b (v_zone).w,d0 ; get current zone ID cmpi.w #id_LZ_act4,(v_zone_act).w ; check if level is SBZ3 (LZ4) bne.s .music_speedshoes ; if not, branch moveq #5,d0 ; play SBZ music instead of LZ ; Obj01_PlayMusic: .music_speedshoes: lea (MusicList2).l,a1 ; load music list for post-speed shoes move.b (a1,d0.w),d0 ; get entry for current zone jsr (QueueSound1).l ; resume normal level music[/CODE] Also, go to the [B]26, 2E Monitors and Power-Ups.asm[/B] file (For older disassemblies, this was still called [B]2E Monitor Content Power-Up.asm [/B]but in current versions. This was merged with Monitors.) Go to the label [B]Pow_ChkShoes[/B] and find this line [CODE] move.w #bgm_Speedup,d0 ; set music speed-up command jmp (QueueSound1).l ; play it[/CODE] Simply replace the [B]bgm_Speedup[/B] music with any music you put in [B]Constants.asm[/B] (Example: bgm_SpeedShoes). [B]Notice:[/B] If you want to do the same thing when you have implemented the different song per acts guide by Selbi (og. by Nineko), just simply replace the lines mentioned with these: [CODE] moveq #0,d0 move.b (v_zone).w,d0 cmpi.w #id_LZ_act4,(v_zone_act).w ; check if level is SBZ3 (LZ4) bne.s .music_speedshoes moveq #5,d0 ; play SBZ music ; Obj01_PlayMusic: .music_speedshoes: jsr (PlayCurrentActMusic).l ; resume level music after speed shoes has worn off[/CODE] I hope you enjoy this tutorial, happy hacking and enjoy the vastly customized music for speed shoes (Like how Sonic CD did.)
