I have a Sega Astro city that has been gutted. It has a tv in it with a scart input. It's been used for a few years with an original Xbox in it running an emulator. I've been thinking of putting a raspberry pi in it to run emulators. I really know nothing about raspberry pi's, should I go for a 3B+ or a model 4? which I just saw is new, but not sure which is more suitable.
I'll need some way to connect it to the screen and output the right resolution somehow. Does anyone have experience with this, or can recommend something?

I see that it doesn't have support for the raspberry pi 4 yet.
And the thing I'm really stuck on is connecting the controllers. I have 2 Sanwa sticks, 2x 6 button layouts and 2 other buttons for start and coin insert. Does anybody have any ideas on how I would connect the controllers and buttons?
