Now supports 82, 83, 85, and 86 Calculators. However, Input
is broken on 82, 83 doesn't even boot right now. And 85 &
86 are basically the same, except 85 is a little faster.
I am porting an old DOS TI Calculator emulator to the DS.
The output will be on top screen, and the bottom will be used
for input. Current version tested on real DS.
