Download the John Ness Emulator on your PC. Follow the steps discussed below to get the amazing NES emulator app on your Windows and Mac PCs.

What is the John Ness Emulator PC app?
John NESS emulator for PC might have a strange name to anyone unfamiliar with the market for emulators on Android, but in reality, it’s just one entry into the popular line of apps developed by John emulators on the Play Store. As implied by the name, John NESS is an NES emulator. Each app has both a lite version and a fully paid version that allows users to select whether or not they wish to have advertisements in their emulators.
When you first load John NESS Emulator for Windows, for the first time, the app scans your system hardware, allowing the main display in the app to display your full list of games. Any dumped ROMs will automatically be loaded into this list, populating the app with information and making it easy to start playing automatically. Selecting your game is as easy as tapping on it with your finger, though you can also choose to browse games through specific folders.
Is it Any Good?
When it comes to performance, we have no major complaints. Everything feels smooth and pleasurable to play, and the audio sounds as crisp and clear as you would expect. There’s no perceptible input lag as far as we could tell when playing through the game, and even the on-screen controls feel excellent to use.
Though you can customize your controls in the settings menu, the standard layout is about as comfortable as you’ll find in an emulator, with the A and B buttons are layered, the D-pad is in an accessible section of the display, and the app automatically goes into fullscreen mode while still displaying the time in the lower-left hand corner.
Unlike most emulators, John NESS Emulator for PC has the option to change your preferred power mode. By default, it’s set to high quality, which allows for smooth video and controls, but you can also select between a power saving mode and an extreme power saving mode that allows for your mobile device to spare some of its battery by lowering the emulation standards.
Power saving mode works to lower the presentation just a bit, while extreme power mode puts a priority on your battery over performance. Neither is the ideal way to play NES games with John NESS, but if you’re worried about your battery life over everything else, they’re solid options.

Features
You can control the look and layout of your app, complete with both layout preferences for portrait and landscape mode, as well as preferred orientation modes. You can control the aspect ratio of your games, which, by default, are set to the original 256×240 resolution (or around 16:15 aspect ratio), but both 4:3 and 16:9 are available in the settings menu for anyone looking to change up how their games look on their tablet. Finally, you have your standard gamepad and virtual-pad settings here to control, including changing how the on-screen controls appear and how your Bluetooth controller syncs with the app.
Final Thoughts
John NESS Emulator for PC is ideal for any NES player looking for a great emulator to take on the go. The performance and quality of the emulator we’ve seen here carries on the John emulator name in a positive way. The addition of power save modes, though at the cost of quality of emulation, is a positive new feature for emulators, which typically require a large amount of power to use.
And little touches, like keeping the emulator active in the background using a notification make it easy to ensure you don’t lose your place throughout the day. Whether you opt for the ad-supported version or pay the in-app purchase to unlock the full app, grab John NESS as your go-to NES emulator.
