README.md

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The GUI has been replaced by a new one (taken from x48ng) in SDL2 and/or ncurses.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

Installing

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
