Hyperpie looks better imho, theme wise than Retropie.
Curious why you went with Hyperpie over Retropie?
I am in the process of building a arcade caninet, and this will go nicely with Hyperpie, thanks OP!
seems like it is possible https://www.reddit.com/r/raspberry_pi/comments/6aki9y/best_way_to_combine_retropi_kodi_and_pihole_for/ you just need to have a bit more knowledge in the pi configuration etc. some of the projects have a pre configured images so they boot automatically without a lot of manual configuration.
Newb question......can you have one of these running pi-hole and at the same time record and stream tv using the pi hat or presumably a USB tuner at the same time?
