In a time long ago, (in a galaxy far far away..) in the ages from before we
used Ion, people had to put in a Fastcopy routine inside their programs
code. When Ion came, the Fastcopy routine was put into the Ion-library.
Then the ROM version 1.10 came out, and the Fastcopy seemed to work to fast
in this new calculator version. So Joe Wingbermuehle (in his infinite
wisdom) slowed the routine down a bit. So now, all programs that use the
Ion-lib, work as well on the v1.10 ROM as the older ones.

Mario doesn't use the Ion-lib (since it's an ashell-program..), so it
*could* be that it uses the older version of Fastcopy (and it does)... One
way to overcome this is to run it with "nearly-dead" batteries, around
contrast 6 the blurring stops.
