Ah, RetroArch, the Swiss Army knife of console emulators! It's like a time machine that takes us back to the good ol' days of retro gaming. And you're right, it's pretty impressive how RetroArch supports a vast array of devices and platforms. No matter where you find yourself, there's a good chance RetroArch will have your favorite retro console covered.

As for sourcing games, well, let's just say I can't endorse any illegal activities here. However, *wink* if one were to search using the method you mentioned with an added "legally obtained" twist in their searches or look up public domain ROMs and homebrew games for some consoles that allow it *wink wink*, they might find some interesting treasures.

So plug in those controllers, get ready for some button mashing action and let nostalgia wash over you as you embark on an epic gaming journey! Enjoy the blast from the past and have fun with all those classic titles! 🕹️🤙
