The Hyperkin RetroN 5 plays nine cartridge formats across five physical slots, outputs video at up to 720p over HDMI, and adds on-the-fly save states to every supported game regardless of whether the original hardware ever offered them. At $179.99, it is Hyperkin’s flagship multi-system console, and it is the single most capable piece of hardware in the RetroN lineup for collectors who want to run a wide library from one box.
The console sits in an interesting spot in 2026. Cartridge prices on the secondary market keep climbing, so anyone who already owns a collection has a real incentive to find a way to play those carts on a modern display without paying for a separate upscaler. The RetroN 5 addresses that problem directly, though it does come with a few trade-offs worth knowing before you buy.
Which cartridge formats does the RetroN 5 support?
Five physical slots cover nine systems. The four slots on top of the unit handle NES, Famicom, SNES, Super Famicom, Genesis, and Mega Drive cartridges. The slot on the front accepts Game Boy, Game Boy Color, and Game Boy Advance carts, and the console automatically identifies which of the three it is reading. That single front slot covering three Game Boy generations is one of the more convenient design choices on the hardware.
The console also carries a universal chipset that removes region locks, so PAL and NTSC cartridges both run without modification. Japanese Super Famicom and Famicom carts work the same as their North American equivalents. For anyone who collected import titles or picked up Japanese cart lots, that matters.
One more system is technically reachable: Sega Master System games become playable if you use an original Sega Power Base Converter in the Genesis slot, though that adapter is sold separately and is increasingly hard to find.
What does 720p HDMI output actually look like in practice?
The RetroN 5 upscales to a maximum of 720p at 60 frames per second over a standard HDMI connection. Compared to running an original NES or Genesis through composite cables into a modern flat-panel, the difference is immediately visible. Composite signals lose sharpness and bleed color on LCD panels; the RetroN 5’s all-digital HDMI output avoids both problems.
The upscaling is honest rather than aggressive. Pixel edges stay clean, and the image reads clearly at typical living-room viewing distances. For players who prefer a softer look, a scanlines filter is built in, and several additional shader options let you adjust the presentation without touching any external hardware. Audio goes through the same upgrade path: the console applies audio interpolation to produce a smoother output than the original chips generated, which is noticeable on Genesis titles with FM synthesis tracks.
One caveat worth naming: purists who prefer playing on a CRT with original hardware will find the upscaled image too clean. The RetroN 5 is aimed at people playing on modern displays, not at CRT enthusiasts chasing pixel-perfect authenticity.
How do save states work, and why do they matter for old cartridges?
Save states on the RetroN 5 are accessible at any point during gameplay by pressing the Home button on the included wireless controller. The console offers 10 save slots per game, and a rear SD card slot expands storage for both save data and screenshots. Screenshots save as JPEG files, which makes sharing a high score or a rare moment in a 30-year-old game straightforward.
The practical value here goes beyond convenience. Many original cartridges from the NES and SNES era used small internal batteries to hold save data, and those batteries are now dead in a significant portion of surviving carts. A cartridge that can no longer store a save file in its own memory becomes fully functional again when the console handles saving externally. That applies to titles like The Legend of Zelda, Final Fantasy, and most RPGs from the 16-bit era.
The console also includes an autosave feature that triggers on shutdown, so a sudden power interruption does not wipe progress. Built-in Game Genie-style cheat codes round out the quality-of-life additions, with codes accessible from the same in-game menu.
What controller options does the RetroN 5 offer?
Every RetroN 5 ships with one Bluetooth wireless controller with a range of at least 25 feet. The controller uses a microswitch directional pad, six face buttons, two shoulder buttons, a Home button, and two programmable macro buttons. Its rechargeable lithium-ion battery charges via a Micro-USB cable that connects directly to the console.
The included controller is functional but not exceptional. Players who grew up with original NES, SNES, or Genesis controllers will probably find the originals more comfortable for extended sessions, and the RetroN 5 accommodates that: six original controller ports (two per system, mounted on the sides) accept NES, SNES, and Genesis controllers directly. Button mapping is fully customizable through the on-screen interface, and the console saves custom layouts so you do not have to reconfigure after each session.
For players who want a dedicated wireless option beyond the pack-in, Hyperkin also offers the RetroN 5 Wireless Controller as a standalone purchase.
The RetroN 5 Is the Right Answer for a Specific Kind of Collector
If you own physical cartridges across multiple classic systems and want to play them on a modern display without buying a separate upscaler, the RetroN 5 is the most direct solution in the RetroN lineup. Nine formats, five slots, 720p HDMI output, save states with 10 slots per game, and region-free play cover most of what a serious retro collector needs from a single box. The trade-off is that it uses emulation rather than original hardware, which introduces occasional compatibility gaps and some input lag on certain titles. For casual-to-moderate retro play, those gaps rarely show up. For tournament-level or precision platforming, they might.
Frequently Asked Questions
Does the Hyperkin RetroN 5 work with original NES and SNES controllers?
Yes. The RetroN 5 has six original controller ports mounted on the sides of the unit, two each for NES, SNES, and Genesis. You can plug original controllers directly into the corresponding port and use them as you would on the original hardware. Button mapping is also fully customizable through the on-screen menu.
Can the RetroN 5 play Japanese Famicom and Super Famicom cartridges without an adapter?
Yes. The console includes a universal chipset that removes region locks, so Japanese Famicom and Super Famicom cartridges run natively without any adapter or modification. PAL cartridges from European releases are also supported, and the HD upscaling applies to all regions equally.
How many save slots does the RetroN 5 provide per game?
The RetroN 5 offers 10 save slots per game, accessible at any point during gameplay via the Home button. A rear SD card slot expands total save storage and also holds screenshots saved as JPEG files. An autosave on shutdown prevents progress loss if the console loses power unexpectedly.
Is the RetroN 5 firmware updatable, and why does that matter?
Yes. Firmware updates are installed via SD card, downloaded from Hyperkin’s website. Updates can improve game compatibility, fix bugs, and refine system performance over time. Keeping the firmware current is the single most effective way to reduce the small number of cartridge compatibility issues the console can encounter.
What is the difference between the RetroN 5 and the other RetroN consoles Hyperkin sells?
The RetroN 5 is Hyperkin’s most format-inclusive console, covering nine cartridge systems across five slots. Other models in the lineup focus on fewer platforms: the RetroN 1 HD handles NES only, the RetroN 2 HD covers NES and SNES, and the Supa RetroN HD is a dedicated SNES console. The RetroN 5 is the right choice when you want one box for a broad mixed collection rather than a dedicated single-system experience.
