Hi, I started to work in the migration of the [x48ng emulator](https://forum.clockworkpi.com/t/hp48gx-emulator/14704) to [Luckfox Lyra](https://forum.clockworkpi.com/t/luckfox-lyra-on-picocalc/16280) Picocal alternative. I have a “in progress” branch over a nice and **easy environment or SDK** using Docker, thanks to [@benklop](https://forum.clockworkpi.com/u/benklop) but I have an execution issue.

## Status update:

- fixed the buildroot issues
- provisional workaround for exit action issue. Now you can exit with F1
- first vesion that works but with some issues, but it is working 😄

TODO:

- SDL2 support
- Improve ncurses alternative
- UART check (maybe is working. For uploading files)

The steps to replicate this are here:

**Status:**

I tested the last version of x48ng, and thanks for its developer, it is working better. I did some changes in my fork, and with `fbterm` and configured with font 8, `x48ng --tui-small --mono` works fine, and almost fit into the screen:
