x50ng ist ein HP 49g+ / 50g Taschenrechner-Emulator, Open-Source in C und ein Fork von x49gp.

• There is now an ncurses based text-mode UI in the same 3 flavors as x48ng: --tui, --tui-small and --tui-tiny
• some optimization/simplification of the display refresh code
• a sadly unsuccessful attempt to port the forked old qemu to aarch64. This will likely require additional work. Likely upgrading x50ng's qemu to a more recent release.

    their alternate function while Shift is active. (This behavior can be
    disabled and enabled using the new STATIC and DYNAMIC settings in the new
    MENUS submenu of the MODES menu.)
