| |
| − | =A Few Fixes=
| |
| − |
| |
| − | ==Death Egg Music Not Playing After Boss (All Revisions)==
| |
| − |
| |
| − | ===Fix===
| |
| − |
| |
| − | Goto '''''loc_39BA4''''' and you'll see this.
| |
| − | <syntaxhighlight lang="asm"> move.b (Level_Music).w,d0</syntaxhighlight>
| |
| − | Change the b to a w.
| |
| − |
| |
| − | ===Cause===
| |
| − |
| |
| − | The Game is trying to read the RAM address as a byte instead of a word which makes it load Sound 00 which is nothing.
| |
| − |
| |
| − | ==Grabbers legs and skids are the wrong way (REV02 Only)==
| |
| − |
| |
| − | ===Fix===
| |
| − | Goto '''''InheritParentXYFlip:''''' and you'll see this.
| |
| − | <syntaxhighlight lang="asm"> if gameRevision<2
| |
| − | andi.b #$FC,d0
| |
| − | move.b status(a0),d2
| |
| − | andi.b #$FC,d2
| |
| − | move.b render_flags(a1),d1
| |
| − | andi.b #3,d1
| |
| − | else
| |
| − | ; Peculiarly, REV02 changes this to only inherit the Y-flip.
| |
| − | ; This causes a bug where some sprites are displayed backwards (Silver Sonic's sparks and Grabber's legs).
| |
| − | andi.b #$FD,d0
| |
| − | move.b status(a0),d2
| |
| − | andi.b #$FD,d2
| |
| − | move.b render_flags(a1),d1
| |
| − | andi.b #2,d1
| |
| − | endif</syntaxhighlight>
| |
| − | Remove the bit after the else and the '''''if gameRevision<2'''''.
| |
| − |
| |
| − | ===Cause===
| |
| − | Revisions 00 and 01 inherits the X and Y flips but for some reason in REV02 (Sonic Classics) they change it to only inherit the Y flip this means the sparks and legs won't be flipped horizontally.
| |
| − |
| |
| − | ==Walking on air in WFZ (REV02 Only)==
| |
| − |
| |
| − | ===Fix===
| |
| − | Goto '''''loc_3B7BC:''''' and you'll see this.
| |
| − | <syntaxhighlight lang="asm"> if gameRevision<2
| |
| − | andi.b #standing_mask,d0
| |
| − | else
| |
| − | ; I don't know what this change was meant to do, but it causes
| |
| − | ; Sonic to not fall off ObjBD's ascending platforms when they retract,
| |
| − | ; making him hover.
| |
| − | andi.b #2,d0 ; 'Y-flipped' bit???
| |
| − | endif</syntaxhighlight>
| |
| − | Like the last bug remove the REV02 check and everything below (and including) the else.
| |
| − |
| |
| − | ===(Probable) Cause===
| |
| − | It's possible that because the game isn't checking that Sonic is standing anymore this causes the game to think Sonic is on the ground.
| |
| − |
| |
| − | =A few optimizations for MegaPCM=
| |
| − | ==Optimization #1==
| |
| − | At '''''Int_Normal''''' and '''''Int_NoOverride''''' you'll see this.
| |
| − | <syntaxhighlight lang="asm"> cp 80h ; stop flag?
| |
| − | jp z,StopDAC ; if yes, branch
| |
| − | jp m,PauseDAC ; if < 80h, branch</syntaxhighlight>
| |
| − | Delete them and replace them with this.
| |
| − | <syntaxhighlight lang="asm"> jp Int_StopFlag</syntaxhighlight>
| |
| − | Then above '''''Int_Normal''''' add this.
| |
| − | <syntaxhighlight lang="asm">Int_StopFlag:
| |
| − | cp 80h ; stop flag?
| |
| − | jp z,StopDAC ; if yes, branch
| |
| − | jp m,PauseDAC ; if < 80h, branch
| |
| − | ret</syntaxhighlight>
| |
| − | This will reduce the size by 1 byte.
