A raspberry pi 4 can emulate any console up to the N64. I’m still running a pi 3. The 3 can’t do the N64 well. I’m unsure how good the pi 4 is with the graphics of the N64.
I can run basically any game published before 1995. It’s just a matter of finding roms. They used to be easy to get, but Nintendo got angry with websites that were hosting them. So now you have to dig a little more to get them.
I spend as much time in one play through the free factorio demo as I’ve played in some AAA games.
In the hours entertained per dollar doesn’t, factorio is stupid cheap.
