I doubt that the Expander Shell will take up more than 4-5k, so that
may or may not be a problem. It will be a while before most games
reach 20k! The only problem with an Expander shell is if a program
accesses other files on the calc during the program, in which case
there must be a way to do multiple file downloads within the shell.
