Does anyone know how to PUT graphics outside of the VIEW SCREEN without getting an error?  I'm trying to perfect my map for my RPG and it uses tiles.  I want it to scroll smoothly (moving each tile 1 pixel instead of 1 tile every time the player moves), however, I can't figure out how to get the tiles to only draw partially so that they smoothly scroll off the screen instead of blink out as soon as one of the pixels is out of the viewing area.
Anyone have any ideas?  I would use SCREEN 7, but I'm utilizing all 256 colors of SCREEN 13 and would like to keep it that way.  My goal is to also program the whole thing by hand so the use of high end graphics libraries isn't an option  to me.
Any ideas?
