This is not much Mac-related, but I am currently spending all of my 'computer time' with preparing two Raspberry Pi 3Bs with Retropie as Christmas presents. I will collect my insights, and again like it was for MAME, my conclusion is that
Macs and Raspberry Pis/Retropie are a good combination.
It is mostly a
MAME 2003 romset. But F
inal Burn Alpha (then with different ROMs) seems to be a very good choice in case of performance problems on the Pi.
After having gone through some learning curve,
I cannot give enough kudos to the Retropie project! What an impressive achievement - including
some really good online documentation that is up to speed with the development. One thing is clear: You can hardly beat this system in the living room when it comes to a smooth retrogaming experience.
I will summarize my recommendations in the following:
