I found a Atari 2600 homebrew game I had to play. But, the Stella in Solus was at version 4.7.3. To be able to play Draconian the Atari 2600 homebrew game. I needed Stella 5.0.2 or better. The newest stable version of Stella is 5.1. So I download the source, extract it. Before compiling. You need one thing, at least I did. That was a package call sdl2-devel. So get that before running the commands. Which are
sudo make install
This will not rewrite over the older Stella version. To run the newest version of Stella. Just go to the file Stella where you compile this at. And run this command at that location.
Now enjoy the game Draconian
