Recently I got all the necessary parts and now have a working Nintendo again after about 16 years, I regrettably gave away the last one I had..
I'm playing through the Castlevania games, starting with the first. It's impressive how much better each one got on a technical level. Super Mario 3 has been getting played as well, I have major nostalgia for that one. And I totally dig River City Ransom, super fun beating people with trash cans!
