two possibiliites in my mind would be:
a) writing a clipping sprite routine (might be nice I suppose...)
b) checking the position of the sprite and if its greater than 88 then mask
out some bits (for example anding 11100000b if it were at possition
91)...you could write the mask routine simply using a djnz and working
backwards...
