When you use crashman's tilemap routine, you can't use any normal sprite 
display code, in fact you shouldn't even think about touching plotsscreen or 
savesscreen (and if you never relocated the 1k block to there, then you lose 
your programs and variables at the end of ram). You have to use the masked 
sprite routine that comes with it, which writes to the Tilemap Compatible 
graphmem.

To move sprites based on new X coordinates vs old X coordinates, just 
subtract the screen's X position from the sprite's X position, then draw it 
there.

You might want to try storing your map data compressed, then there are no 
line length problems.  If you want to take compression even farther, you 
could attempt Nintendo's very own system that they used in Mario 1.  They 
fit all world 1-1 through 8-4 into less than 5000 bytes of space!
