this could be written by hand. Just find out the length of the string and
go through it backwards. multiply it by 10^position and add it to the
total until you reach the end of the string.

if your program is this large, i would suggest you optimize and trim the
fat. Take out the title picture, and unneccesary additions to the program
(graphics waste alot). See if you can use temporary memory instead of your
program. Find code that is repeated often and consolidate it into a
call. use compression with maps/graphics/etc. Unless you have already
done all of this, you should never have to deal with using a loader.
