VBL SCROLLER

This is a small doc which is made to help you understand the 
scrollerroutine in the ASSEMBLER folder better.
The routine is made by TLT,The Light Team,and we say thanks to 
you who were kind to give it out.Many groups don't want to spread 
their routines to other people,not even the bad ones (?!).
Anyway,even if I am a total looser when it comes to assembler,I 
can understand a little piece of this routine.
It is a quite simple routine.Only one 16X16 font which is 
scrolling and nothing else.Not a picture,no music.
Well,I will explain the easiest things in this routine,even 
though it's not necessary.
The font is made in neochrome (Yak!Worst paint program I've ever 
seen!).To look at it,load Degas Elite or the bad program 
Neochrome or any other program which can load neo pictures.
Now you can change the font to look exactly how you self want it 
to look,but it must remain the same size as the original (16X16).
Save the font (remember it must be a .neo extension!) and then 
load Devpac 2.Load the source named SCROLL.S by clicking on Load 
in the menu.
When you have done this,choose find in the menu,write   
FONTBUF: and then press NEXT.When you have done this,you will 
come to the label FONTBUF.There you can write the name of the font.
You have to have the font on the same disk as the routine,because 
it will write them to one file later.
After you have done all this,you can go a few lines down to the 
label SCROLLTXT.There you can write your own scrolltext,how much 
as you want.And if there becomes any problems (if you think you 
have written too much scrolltext),then you only have to increase 
the buffer.This you can do by going one line under the scrolltext 
and increase the number.
E.g.          DS.W  2560

to

              DS.W  3000

To increase the buffer with 440 signs.
Well,I think that is all I need to explain.If you'd like to put 
in a picture,some music and maybe some sprites,then do it by 
yourself!That's always the best result!
