"My son is now suddenly interested in Pokémon after seeing a reboot show on Netflix and now I want to go down memory lane with him but need help…"

So I played a few Pokémon games wayyy back (Like Red and Blue days lol). But I’m old now and haven’t touched a GameBoy in I don’t know how many years. How do I go about finding a decent GameBoy Advance SP? I see that a lot of people refurbish them and then sell them with new screens/shells. Is it worth it to just buy this or should I try to do it myself on an old one? And we want to play all the Pokémon games in chronological order. As I recall you can trade between systems with a link cable? What is it and where can I source one? Are there new “reproduction” cartridges that work better than old ones or is it the other way around? Sorry for all the questions I just want to make sure his games save and everything as I know I am about to open Pandora’s box. I already made the mistake of teaching him M:tG via /r/pokemon https://ift.tt/3jA3XdE
