/vr/ - Retro Games

Ok, so I was interested in the NES Classic, but honestly it being sold out within seconds and me working an actual job ie no chance in hell of getting it, since there was no pre-orders or pick up in store, kinda made me say fuck nintendo.

So anyways, I am thinking of the raspberry pi, that way its more than 30 nes games, plus other systems, so my questions are...
..1) I should get the raspberry pi 3 model b, im guessing? Seems cheaper than 2.
2) How well does it emulate the nes, snes, etc?
3) Should I just get the pi itself? I was thinkin I could use a genesis case, as a case, tho Id have to cut wholes in it, dunno if I have a knife that can do that.
4) where to buy it? Off what site, Im guessing stores dont sell it.
