RetroArch is widely considered one of the best ways to emulate retro systems across many devices, but it is also a little bit daunting for beginners.

In this RetroArch guide, we show you how to user RetroArch, taking you through each step, from download and installation to configuring emulator cores.

This allows RetroArch to support a huge amount of classic games, covering systems from the Atari 2600 to the Sony PlayStation 2, as well as arcade games.

Step 3 – Open RetroArch

Once you have successfully installed RetroArch, open the application and you will be presented with the main menu. You can navigate around the menu via your keyboard or any controller that may already be connected (RetroArch will auto-configure a number of wired and wireless controllers).

Basic navigation with the keyboard is easy though. Use the arrow/cursor keys to move around the menu, press return to select a menu option, and backspace will take you back a step to the previous menu/selection.

Step 4 – Installing your first Emulation ‘Core’

This simply means you will now install the emulator of your choice. In this example, we are going to download a libretro core that emulates a number of Sega systems, including the Sega MegaDrive/Genesis. You need to select ‘Load Core’ from the first menu (The one with the Space Invader-like icon), then scroll down and select ‘Download a Core’.

This will take you to a long list of emulation cores where all the system names for them are listed. We want to scroll down to the core which is called ‘Sega – MS/MD/CD/32X (PicoDrive). PicoDrive is the name of the emulator core which will power our MegaDrive/Genesis emulation. Select this core by pressing return, you will notice the yellow text at the bottom of RetroArch confirming the download of the emulation core.

Step 5 – Booting A Game In RetroArch

Now you have the emulation core installed, You’re essentially ready to go! Fortunately, RetroArch automatically configures many controllers, so if you already have your controller connected, there is a good chance you’re ready. If you find your controller is not responding, visit for details on how to configure controls manually.

So, here is the (potentially) tricky part, you may be asking “Where can I download a game a ROM/ISO?”. A ROM/ISO is a copy of the game cartridge/tape/CD/DVD which can be loaded into the emulator to play.

Downloading game ROMs as you may already know is a contentious area, but generally speaking, a good place to start is to own the actual game prior to hunting down a copy of the ROM/ISO. We cannot directly recommend any sites or resources for these materials, but a quick search online will soon make things apparent!

Let’s assume you have a MegaDrive/Genesis game ROM to load into the PicoDrive core. All you need to go back to the main menu and select ‘Load Content’. Next, select the drive (e.g. C:) and locate where the file is stored. Once you have found the file, select it and the game will load.
