Hello people...

I have a question...I am making a platformer that (obviously) uses side
scrolling...

Now, I would like to use parallax scrolling but it is very difficult (well
not really, but it does take longer)...so, I thought I would keep it simple
and use Mode 13H...use a virtual bitmap and just blit it to the
screen...this would serve as a scroller and a double buffer..

Here is the potential problem...using a screen of 3200x200 (10 screens
wide)  the memory would require 640,000 bytes!  
The good news is that this method makes it VERY easy to program and there
is less drawing (I would just blit the entire map at once then blit the
portions to the screen).

The bad news is the huge memory requirements...however, I am using 8 megs
for the game so that it might not be a problem after all...

What is your opinion?

Please respond with lots of opinions...it helps my judgement of where I
should go with this...

Thanks...

PS -> it's a sci-fi platformer...
