DS-HPCALC is a project to port the Nonpareil calculator emulators, originally written by Eric Smith, to the Nintendo DS Lite.

Installation

It contains 2 emulators (DLDI patch if needed):

• HP11C.NDS - Emulates the Hewlett Packard HP-11C.
• HP16C.NDS - Emulates the Hewlett Packard HP-16C, both fully programmable, programmers calculator with persistent memory.

User guide

The first time you turn on the calculator/homebrew it will display Pr Error. This is normal behaviour and indicates that the persistent memory has not been initialised yet.

The calculators maintains their persistent memory in a file on your loader. Memory is only written to the file when the power button on the calculator is pressed to turn the calculator off (virtually).

Screenshots

Compatibility

The calculators were built with the devkitPro r21 and use libfat to implement the calculators persistent memory. These are the loaders tested by the developer:

R4 Revolution
M3DS Real

Credits

NONPAREIL All of the intelligence in the calculator emulator was written by Eric Smith.

Most of the underpinnings of the calculators is provided by the Woopsi User Interface library, which can also be found on SourceForge.
