IIRC I only used five sprites in Cubis. And I had to generate the
display data in RAM, since there just isn't enough time per
scanline to generate that much data on the fly. If you don't
want to use the Supercharger and don't have enough RAM to spare,
you'd have to use the 100 predefined graphic characters in ROM,
as you suggested. But they would only require 500 bytes, since
you don't really need to store the empty line at the end of each
number. If you are going to use a bankswitched setup anyway,
500 bytes might not be too much of a problem to fit in.
