James,
Hello. It is late at night and my mind is rapidly deteriorating so I have to 
make this short. I just today figured out how to make a background scroll. (at
least at an affective speed, about 20 fps on my computer.) The assembly 
language routines I have written are:

VGA1.COM - Copys a portion of memory to the screen

VGA2.COM - Can't really remember what this one does. 
I don't use it in the program.

VGA3.COM - Draws the map to specified memory area.

VGA4.COM - Draws a set of sprites to a specified memory area.

The program GAME3.BAS is an example of how these routines can be used 
together (It also will probably develop into a game.) PAGEING.BAS is the map 
designer. I am also going to use these routines in my RPG game. I hope you 
can use them for your programing needs. They are not MODE X, they are regular 
screen 13 so you can use any of the normal graphics commands with it.

The files for this program are:

GAME1.LVL - Map file

GAME1.PIC - Map Graphics file

GAME1.CHR - Character Graphics file

GAME1.PLL - Palette file

BLKDIS.DAT - Block identifier file

The controls for the game demo thing:

[SHIFT] - Run

[ALT] - Jump

Left/Right arrows - Walk

Down arrow - Slide

The controls for the map editor:

[,] - Decrement block number

[.] - Increment block number    

  [I] 
[J][K] or Right mouse button - Move screen     
 [M]

Left mouse button - place block

I have also include SVGADRW2.BAS which is the beginings of a 16.7 million color 
drawing program. I doubt I'll ever use the 16.7MCM becuase it runs slower than
256 color mode. You can make great affects with it though.

BYE
