Is the MarlinSimulator being maintained? How do I use for a rotary button and an SD card?

Working off https://github.com/Ultimaker/Ultimaker2Marlin

I can build and run MarlinSimulator (W7Pro, Code::Works 16.01 with MinGW, SDL 1.2.15, all freshly installed), and get to here:


Clicking anywhere or pressing random keys does nothing (OK, ESC exits!).

Clicking on the red square turns it to green, and then the firmware displays an error message:


Am I doing something wrong? There are no instructions on how to run the beast (I'm grateful it even exists!). Has anyone other than Daid successfully run it?

It's intended to be used with the arrow keys and the enter key (ok, and ESC :)).

And it needs a bit of patience - depending on the menu it needs sometimes more than one key stroke on the arrow keys to move the selection.

Does it not function?

oh, ...and put the mouse aside...

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
