# Emulator of the HP 48GX, HP 49, and HP 40

**This is a fork of saturn v4.1.1.1 originally by Ivan Cibrario Bertolotti.**

Original source are available at https://www.hpcalc.org/details/4382

The GUI has been replaced by a new one (taken from x48ng) in SDL2 and/or ncurses.

The main binary is `dist/saturn` with helpers/wrappers scripts available per model as:
* `dist/saturn48gx`
* `dist/saturn48sx`
* `dist/saturn49g` (not really functional (yet))
* `dist/saturn40g` (not really functional (yet))

## Building

Dependencies:
- SDL2
- ncursesw


``` shell
make
```

## Installing
``` shell
make install DESTDIR=/
```

## Using
Use the wrappers scripts.

The local data are stored under $XDG_CONFIG_HOME/saturn<model>/
