I bought my Pi-top 3 via Ebay recently to try and run the Pimiga build that has all the bells and whistles. Unfortunately, I cannot get that one running.
I did manage to get Rasatari (Atari ST emulator) going and it works pretty good. Added a gazillion ST game files. Love having a laptop and a beautiful screen for emulation.
Any existing build of retropie I had laying around runs great too.
How about others? Any luck getting your favorite 8 bit or 16 bit build running on the Pi-top 3?
Kudos to the maker of this product! LOVE it!
