HP11C.nds is an emulator of the Hewlett Packard HP11C Scientific calculator.
HP16C.nds is an emulator of the Hewlett Packard HP16C Programmers calculator.
All input is through the touch-screen.
Both calculators provide persistent memory, by saving a file to your loader cartridge. It uses libfat
so should be dldi compatible - patch it if you need to. Memory is only saved when you press the
calculator power button to turn the calculator off. This does not reboot the Nintendo, it just saves
memory, blanks the calculator screen, then waits to be turned on again.
The first time the calculator starts up, it may display "Pr Error" - this is normal behaviour. Press
any calculator key to continue.
With the exception of the HP12C and the HP15C, it is not feasible to port any of the other calculators
that nonpareil supports, due to screen/keyboard sizes. It was a mean feat squeezing the 11 and 15's
keyboards down without losing visibility. However, if you want to give it a try, feel free, the sources
are freely available.
Both calculators are hobbled by the GPL2, see the files LICENSE and COPYING for more information.
If the source code was not provided in the archive with the binary, then it should be available at
the same site you loaded the binaries from.
