# Emulator of the HP 49G, HP 48 (GX & SX), and HP 40G
|
||
|
||
**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The GUI has been replaced by a new one (taken from x48ng) in SDL2 and/or ncurses.
|
||

## Building
|
||
|
||
Dependencies:
|
||
- SDL2
|
||
- ncursesw
|
||
|
||
|
||
``` shell
|
||
make
|
||
```
|
||
|
||
## Installing
|
||
``` shell
|
||
make install DESTDIR=/
|
||
```
|
||
|
||
## Using
|
||
The main binary is `dist/saturn` with helpers/wrappers scripts available per model as:
|
||
* `dist/saturn48gx`
|
||
* `dist/saturn48sx`
|
||
* `dist/saturn49g`
|
||
* `dist/saturn40g` (not really functional (yet))
|
||
|
||
The local data are stored under `$XDG_CONFIG_HOME/saturn<model>/`.
|
||
|
||
The scripts will take care of creating `$XDG_CONFIG_HOME/saturn<model>/`, download an appropriate ROM from hpcalc.org and create RAM cards (for 48gx and 48sx models.)
|
||
|
||
## Known bugs
|
||
- some bugs in emulation:
|
||
- 48gx: ON-D A can hang because it tries to write data in ROM space
|
||
- 48gx: VERSION spouts messages in the console (hidden unless `--verbose`)
|
||
- 49g: spouts messages in the console every second (hidden unless `--verbose`)
|
||
- ncurses UI: becomes unresponsive (but still quits gracefully on F7)
|
||
|
||
## Todo
|
||
- fix emulation bugs
|
||
- 49g: find a way to enable the bigger screen (131×80)
|
||
- 40g: make emulation work
