x48ng, a x48 « restomod »

[gwh]

Hi everyone,

Let me present to you x48ng

I've been working on a fork of x48 for some time now. This fork aims at modernizing the code and the user interface.

I think I have arrived at a state where I've made significant changes (which I think of as improvements) and departed enough from legacy x48 that a proper introduction here makes sense.

The main changes are:

• Code:
  

  --tui
  a text mode interface. Using ncurses and unicode the LCD can be displayed in the terminal, in three sizes.
• an complete rethink of the command-line options and configuration file
• …many more small things
  

The Readme has more details and screenshots.

This is for me a pure hobby project, on which I work mainly in bursts of inspiration for the pleasure of it.

Hopefully it's useful to some of you. Have a good day.

EDIT: a « screenshot »:

Glad to see x48 being worked on, I kept installing it over the years on my Linux systems as I upgraded them. Thanks!

I've been using x48 for forever also.

I like the idea of a terminal mode

something with lua, what version of lua do you have/use?

Code:

bash-5.1$ make WITH_X11=no WITH_SDL=no

Here I have lua 5.4.6

EDIT: I just pushed a commit to the main branch that might solve your two errors. I can't really test quickly with an older lua (I suspect you have 5.1.x) but I hope it works for you.

[EugeneNine]

Yes, I have the old 5.1
I miss the old C64 ACSII (petscii) where we had characters that were 1/4 size so we could make tui smaller
here is a pic of old and new side by side

Thank you for your helpful feedback.

Have you tried x48ng --tui --small or x48ng --tui --tiny --mono ?

Both variants use unicode characters to display multiple pixels per character.

• x48ng --tui --small uses http://unicode.org/charts/nameslist/n_2580.html to have 4 pixels per character,
• x48ng --tui --tiny --mono uses http://unicode.org/charts/nameslist/n_2800.html to have 8 pixels per character
  

[EugeneNine]

Ahh yes, I failed to RTFM.
Works on arm, this is on a BeagleBone Black

To get some more experience on historic 48+ calcs I tried to use Emu48 and x49gp.

But finally I was glad to have found x48ng, because e.g. I have tinkered around how to get a proper resolution of the X application x49gp on wayland compositor running PCs (although for Emu48 and wine not a problem ...)

With x48ng it worked to get a usable emulator with easy setup of roms, and readability on a high res screen. (FYI on arch I had to install sdl_gfx for compilation.)

This call works to get a scaled window:

Code:

SDL_VIDEODRIVER=wayland x48ng --sdl

It's encouraging to see my project be useful out there, thank you.

Regarding Arch, another kind user is maintaining packages https://aur.archlinux.org/packages/x48ng (and bleeding edge https://aur.archlinux.org/packages/x48ng-git too)

I'm very glad you find it useful!
