[comp.sys.amiga] Wild Copper Demo Question.

sutherla@qtp.ufl.edu (scott sutherland) (02/25/90)

	I was able to download the Wild Copper Demo (rvb, I think
it's called) and get it running.  I have read in this group that 
there is text which scrolls on the bottom or top of the demo but
is difficult to see without a PAL Amiga.  Well, being the "creative"
person I am ;*), I just used the vertical hold on my monitor to move
the bottom of the screen to the middle.  However, when I did this, I
saw something very strange.  I could see the text scrolling, but the
top half of the text was at the bottom of the image and the bottom half
of the text was at the top half of the screen (by screen, I mean the 
graphic image).  So what I saw was something like:


	|-----------------------|
	|   Bottom half of the  |
	|    Demo image		|
	|			|
	|			|
	|Top 1/2 of all letters |
	|-----------------------|
	|\\Black space between\\|
	|\top and bottom of pic\|
	|-----------------------|
	| Bott. 1/2 of letters  |
	|			|
	|   Top half of the 	|
	|     Demo image	|
	|			|
	|-----------------------|



Does this diagram make sense?  If so, anyone have ideas as to why this is
happening?  Is it something I have set wrong in my Workbench or in my
hardware?  What else might it be and how can it be fixed?

Thanks,

 The Wild Copper RVb Demo has the weird effect of putting half the text 
on the bottom of the screen and the rest at the top on all NTSC Amigas 
that I have seen.
 
 There are programs you can get which will set your computer to PAL if 
you have 1 megabyte of CHIP RAM (actually it has to do with having the 
Agnus which allows 1 megabyte of CHIP RAM; 8372).

        It's not your hardware or workbench.  The reason for this is the way
the demo was programmed.  All that would be needed to fix it, is to change one
number in the program.  Unfortunately, one would probably have a rough time
finding this number in the program without a knowledge of copperlists.
- hope this helps
