Hello
I bought a pi 4 and as so many peepz want to install a retrostation at home.. now researching for hours it seems there are gigantic 250+ gigabyte images to download that include a lot of systems.. my question is however, as the pi has no internal storage how does this work?
Do you really need to buy a 512gb microsd card? Can you use a external USB drive or ? I am a bit confused.
Thanks!
