This is a Nintendo original glitch. It deals with platforms. https://www.youtube.com/watch?v=1nzyWWDYSvc

Here is the fix and what to do in the SMB2J disassembly. (The code that I created I've added a note with my name next to it.)


SetCollisionFlag:
     ldx ObjectOffset           
     pha                            ;shane
     lda Player_Y_HighPos  ;shane
     cmp #$01                  ;shane
     bne platfix                 ;shane
     lda Player_Y_Position  ;shane
     cmp #$df                  ;shane
     bcc platfix                 ;shane
     pla                           ;shane
     rts                           ;shane
     platfix:                    ;shane
     pla                          ;shane
     sta PlatformCollisionFlag,x
     lda #$00
     sta Player_State
     rts
