Check out my game library at
http://www.geocities.com/SiliconValley/Horizon/8630/
The library is specially designed  for 2D platform & action arcade
games. It can run at 70 frames/sec
while scrolling at a maximum of 16 pixels/frame.  That speed is
supported for VGA  modeX 320x200 and every VESA 2.00 mode with 256
colors.

Some of BETATRON's features are:

         and handling - priority lists for sprites
         pixel precise collision detection routine
