Batocera Linux
I wanted to make a retrogaming platform for my nephews, and this project turned into me briefly maintaining a fork of the Linux kernel for the Batocera project, as well as user contributions to the Armbian project and more minimal Deb Image Builder project. My work was focused on ARM boards with the RK3588(S) chipset, such as the Rock 5B and Indiedroid Nova. I also managed to get a cool patch into the underlying buildroot tool to bidirectionally graph package dependencies.
As for the retrogames, the kids love ’em.
