Wouldn't it be great to be able to play all your favorite Pokémon games on your PC? You can do so using ROMs and emulators. ROMs are digital duplicates of game cartridges, while emulators are applications that simulate game consoles. You'll need to download a separate emulator for each game console you want to simulate on your PC. For Pokémon, this includes Game Boy, Game Boy Color, Game Boy Advance, and Nintendo DS. You can also play ROMs online using an online emulator without downloading anything at all. This wikiHow teaches you how to play Pokémon games using an emulator on your Windows computer.
