If I wanted to get classic Pokémon games on my 3ds (Pokémon Yellow, for example), would the best way to be to just buy them from the app store or can I somehow download them from the Internet? Would I use Homebrew, and if so, can someone walk me through downloading it and using it to get those games? I'm pretty sure my 3ds version is past being able to Homebrew. Can I do something to revert it to an earlier version?
