>How do you get started with emulation?
By playing emulating pokemon games on vgba. It was around 10 years.
>Do you just download individual emulators or use something like mednafen or retroarch?
Individual emulators are usually more refined than ones that support multiple consoles with some exceptions as Dolphin or mGBA.
>What's the best approach?
Test multiple emulators yourself and decide later what you want to use.
