Most modern TVs have no idea what to do with an original NES signal, and that is exactly the problem the Hyperkin RetroN 1 HD solves. At $39.99, it accepts your original NES cartridges and outputs 720p over HDMI, giving any flat-screen television a signal it can actually use. The tradeoffs are real and worth knowing before you buy, but for the majority of people who just want to play their NES collection on a 2026 television without a rat’s nest of adapters, this console earns its price tag in the first ten minutes.
Does the RetroN 1 HD actually work on modern TVs?
Original NES hardware outputs a composite signal that most modern flat-panel TVs either reject outright or accept with heavy input lag and visible artifacts from poor internal upscaling. The RetroN 1 HD solves this by running the signal through its own onboard scaler before it ever reaches the TV, converting it to 720p HDMI output that any modern display recognizes immediately. You plug it in, select the correct HDMI input, and the picture appears without fuss. For a $39.99 device, the absence of that setup headache is worth more than it sounds.
The console ships with an HDMI cable, a USB power cable, and one controller, so you are not hunting for accessories before your first session. The controller uses a familiar NES-style layout with a D-pad and two face buttons, which is the correct choice for a device built around original NES cartridges.
What NES cartridges does the RetroN 1 HD support?
The RetroN 1 HD accepts standard North American NES cartridges, the 72-pin format used throughout the NES library from 1985 onward. That covers the overwhelming majority of the NES catalog: Super Mario Bros., Mega Man, Castlevania, Contra, Metroid, and several hundred more titles. The cartridge slot is a top-loading design, which tends to be more forgiving with older cartridges than the original NES front-loading mechanism that developed a reputation for finicky pin connections.
What it does not play: Famicom cartridges (the Japanese 60-pin format) and unlicensed cartridges with non-standard board configurations. If your collection is primarily North American retail releases, you will not run into that wall often. Famicom collectors will need to look at something like the Hyperkin RetroN 5, which handles multiple formats including Famicom, Super Famicom, Game Boy, and others.
How does the picture quality compare to original NES hardware?
This is where expectations matter. The RetroN 1 HD outputs 720p, not 1080p or 4K. On a 55-inch or larger screen, NES graphics at 720p look like NES graphics scaled up: blocky, pixelated, and exactly as the games were drawn. Whether that reads as charming or jarring depends on what you grew up with. Players who remember these games on a CRT will notice the difference in scanline texture, but the image is sharp and stable in a way that composite-to-HDMI adapter chains rarely achieve.
Input lag is low enough that fast-reaction games like Contra and Ninja Gaiden play without obvious delay. No independent lab measurement is published for this specific unit, but the general consensus among players in 2026 is that the lag falls in the acceptable range for NES titles, which were designed around CRT response times to begin with.
Is $39.99 a fair price for what you get?
At $39.99, the RetroN 1 HD sits in a specific bracket: above the cheapest no-name clone consoles that use emulation chips and introduce compatibility problems, and well below the $179.99 Hyperkin RetroN 5 that plays cartridges from five different systems. The RetroN 1 HD uses hardware-based NES compatibility rather than software emulation, which is part of why its cartridge support is reliable across the standard library.
Competitors at similar prices tend to either bundle more systems with worse per-system compatibility or use emulation that introduces audio timing issues on specific titles. For someone who owns NES cartridges and wants exactly one thing, a clean HDMI signal from those cartridges on a modern TV, the $39.99 price point is honest. You are not paying for features you do not need, and you are not getting a device that cuts corners on the one job it was built to do.
The RetroN 1 HD Is the Straightforward Answer for NES on Modern TVs
If you own a collection of North American NES cartridges and a modern flat-screen TV, the RetroN 1 HD does what it promises without requiring you to become an AV technician first. The 720p HDMI output is stable, the top-loading cartridge slot handles standard carts reliably, and $39.99 is a fair price for hardware-based compatibility rather than emulation. It is not the right device for Famicom collectors or anyone who wants multi-system support, but it was never designed to be. For the specific problem it solves, it solves it well.
You can find the Hyperkin RetroN 1 HD directly from Hyperkin at $39.99.
Frequently Asked Questions
Does the Hyperkin RetroN 1 HD work with original NES controllers?
The RetroN 1 HD includes one controller in the box and has a controller port that accepts original NES controllers using the standard 7-pin connector. If you have original Nintendo controllers from the 1980s or third-party controllers built to the same spec, they plug in and work without any adapter or configuration.
Will the RetroN 1 HD play NES games on a 4K TV?
The RetroN 1 HD outputs at 720p over HDMI, not 4K. A 4K television will accept the 720p signal and upscale it using the TV’s own processor, which means picture quality at that stage depends on your TV’s upscaler. The console itself does not output beyond 720p, so expect a standard HD image rather than a native 4K picture.
Does the RetroN 1 HD use emulation or real NES hardware?
The RetroN 1 HD uses a hardware-based approach to NES compatibility rather than software emulation, which is why it maintains reliable support across the standard North American NES cartridge library. Software emulation consoles at this price range tend to introduce audio glitches or compatibility gaps on specific titles that hardware-based designs avoid.
What is included in the box with the RetroN 1 HD?
The RetroN 1 HD ships with the console, one NES-style wired controller, an HDMI cable, and a USB power cable. You will need a USB power source such as a wall adapter or a TV USB port, and you supply your own NES cartridges. No additional cables or accessories are required to start playing.
How does the RetroN 1 HD compare to the RetroN 5 for NES games?
The RetroN 1 HD plays North American NES cartridges only and costs $39.99. The RetroN 5 plays NES, Famicom, SNES, Super Famicom, Genesis, Mega Drive, and Game Boy cartridges and costs $179.99. If NES is your only format, the RetroN 1 HD is the practical choice. If you collect across multiple systems, the RetroN 5 covers far more ground.
