Well.. if you mean a map that is one big bitmap instead of an array of tiles, then all you have to do is blit the rectangle that you want out of the bitmap. Just clip it to the screen edges..

I dont know if that''s what you meant though.

The best way is to setup a giant playfield and use hardware registers to scroll the map. However, I don''t think this works on all new cards...that is unless you use EGA mode.

Ah, it was SO easy to get an Amiga hardware scrolling map two playfields deep at 60 fps. I sure miss that computer!
