How To Set Up RetroArch For NES

The NES by Nintendo was, without a doubt, the console that brought back gaming after the disastrous video game crash of 1983 in the US. It launched Nintendo into the household name it is today and people still love to play the old NES classics.

RetroArch is one of the best places for NES emulation, along with the Nestopia core, you can be up and running in no time whatsoever.

The Nestopia core is what we will be using today in this RetroArch NES set-up guide.

Requirements

  • Install RetroArch – Download RetroArch Here
  • Have at least one NES game ROM ready to test – These are usually .nes, .fds, .unf & .unif files.
  • To play games, you will ideally need a controller – You could use keyboard controls, but you’ll have far more fun using a controller! The 8bitdo Pro 2 Bluetooth Controller is an excellent all-around controller for emulation and can also be connected by USB for even better performance in terms of latency.

Alternatively, for a more NES-like experience, why not use one of these USB NES replica controllers?

Step 3 – Nestopia Core Settings

The Nestopia core has plenty of useful settings to help get your NES emulation experience tweaked to perfection.

Some of the cool features include video filters that simulate old CRT screens and connections such as Composite Video, S-Video, RGB SCART & Monochrome visual effects, for the ultimate nostalgic experience!

Other nice tweaks include removing the NES sprite limit of 8 sprites per scanline, which eradicates sprite flicker, as well CPU as overclocking functions.

To access these settings, press F1 or the hotkey you have set up to pause emulation to access the quick menu in RetroArch, then scroll down the menu until you get to and select ‘options’.

This will then give you access to all the Nestopia core emulator options, including those detailed above.
