lets say that you identified the sprites of the intro, they are (i.e.) 10,0; 10,1; 10,2... 10,n
now open your DEF file and search for an action that uses tht group of sprites
[Begin Action 6]
10,0, 0,0, 5,, a
10,1, 0,0, 5,, a
10,2, 0,0, 5,, a
10,3, 0,0, 5,, a
.........
10,n, 0,0, 5,, a
you have identified action No 6 as the intro (6 is an example)
now search for an anim element tha uses ation No 6
[BG Something]
type = anim
actionno = 6 <----------
delta = 1.80, 2
mask = 1
layerno = 0
That one is the intro, just delete it or comment it with ";"
