Yep, that's pretty important. Obviously, the older (and low-powered) versions don't need much, but the Pi3 and Pi4 need a surprising amount
of power...2.5 and 3 amps, respectively!

Yep I've found this out just in recent days, I don't own a Pi4 but noted a different supply for it when I went looking.

I like the Pi it reminds me of the BBC Micro B I used to use as a kid, and also the cool Microbit that is now in schools and carrying the flag for the 2020s effort with kids.

There's a different connector on the Pi4. USB-C instead of Micro-USB. And, of course, the extra half amp of power draw.

Doesn't RetroPi have emulators for a bunch of old systems? Don't quote me,
but I think there's a BBC Micro emu...I know there's Amiga and C64...
