Best Retro Console Upscalers of 2026

Updated October 3, 2026 4 products scored

An old console and a new TV don't speak the same language. Your console sends out a 240p signal; your panel wants 1080p or 4K, and left to its own devices it makes a mess of the translation — soft edges, wrong colors, and input lag you can feel in your thumbs. An upscaler sits in the middle and does the converting properly, which is why the right one turns a fuzzy, frustrating setup back into the games you remember.

The part nobody warns you about is latency. A box that adds a few frames of delay turns every jump into a guess, and no amount of extra sharpening makes up for that. My team spent seven months running ten of these between old consoles and modern panels, and the ones worth keeping are the ones you stop noticing mid-boss-fight — small enough to disappear under the TV, sturdy at the ports, and set up in five minutes without opening the manual. The picks below cleared that bar; the notes on each explain where the rest fell short.

Sharp, pixel-perfect 240p is the whole point of the Kaico OSSC. Feed it a clean RGB signal from a SNES, Genesis, Saturn or PS1 and the line multiplier repeats each scanline two to six times over, so the image fills a modern panel without the blurring a TV's own scaler adds. The v1.8 board here also brings a 6x mode with pixel repetition and an HDR mode, which makes it the revision to pick if you're choosing between OSSC listings.

We think this is the best picture in the group. Sprites stay square, text stays legible, and colors come through clean instead of smeared — the difference between an old game plugged into a new TV and an old game that looks like it belongs there. It's also the most solidly built unit here; the case feels substantial, which matters when a stiff SCART cable is levering it off the shelf.

Latency is a non-issue. The multiplication happens as the signal passes through, so timing feels like the console rather than like a TV's game mode, and fast shooters stay playable. The trade is the menu. There are dozens of settings, the printed instructions are thin, and you'll spend an evening working out which mode suits which console — 240p sources want one treatment, 480i another.

You'll also need a decent RGB SCART cable, which doesn't come in the box, and a thin unshielded one undoes much of what the scaler is doing. Then test everything you own in the first week: sync is the one variable that sometimes needs coaxing, PS2 in particular, and it's better to find that out while returns are still easy.

Pros

  • 2x to 6x line multiplication for crisp 240p
  • Effectively no added input lag
  • Sturdy, well-finished build
  • HDR mode and the latest 1.8 firmware

Cons

  • RGB SCART only: no composite, S-video or N64
  • Deep settings menu with thin printed instructions
Our verdict

If your consoles can output RGB, this is the one we recommend: the sharpest 240p in the group, no meaningful lag, and the sturdiest build.

480i is the awkward part of retro gaming. PS2, Saturn and Dreamcast libraries lean on interlaced modes, and most budget converters deal with them by throwing away half the lines, which is why the picture jitters. The Mcbazel GBS-C handles 480i with motion-adaptive deinterlacing instead, resolving it into a stable progressive image you can sit through a four-hour session with.

That's the reason we rate it so highly for a collection with a lot of 3D in it. Scanlines can be switched on for 240p titles, the three RGB gain knobs let you kill a green cast without digging into a menu, and there's separate 3.5mm audio in and out — a small thing we appreciated more than we expected, since it means headphones or a soundbar without unplugging the TV.

Inputs are broader than the OSSC's: RGBS/SCART, YPbPr component, VGA up to 60Hz and RGBHV, with HDMI or VGA out at anything from 640x480 to 1280x1024. That covers component-cable PS2, Xbox and Wii, Dreamcast over VGA, and SCART consoles. The web interface you reach from a phone is the surprise — typing values on a handset beats clicking a wheel through a menu any day.

Build is where our enthusiasm cools slightly. The case is light, and screen tearing traced to a faulty unit is a possibility worth planning around rather than a story to dismiss. Buy somewhere with an easy return and run a long session straight away; get a good one and it's the most versatile box here for a mixed 240p and 480i shelf.

Pros

  • Motion-adaptive deinterlacing fixes 480i flicker
  • Takes SCART, component, VGA and RGBHV
  • RGB gain knobs and separate audio in/out
  • Scanline options for 240p games

Cons

  • No composite or S-video inputs
Our verdict

For a PS2, Saturn or Dreamcast library, we reach for the GBS-C first: real deinterlacing, SCART and component in one box, and scanlines when you want them.

Output
480p NTSC / 576p PAL over HDMI

Composite and S-video jacks are what set the RetroScaler2x apart — nothing else in this group has them. If your N64, NES or GameCube is unmodified and an RGB mod isn't on the cards, this is the box that gets you onto HDMI with the cables you already own.

What it does is modest and, for a lot of people, enough. It takes 240p and 480i up to 480p, or 576p for PAL sources, which stops a modern TV's scaler from turning everything to mush. On a set that handles 240p badly, that alone is the difference between playable and smeared, and it handles the consoles that give the pricier scalers nothing to work with.

The Filter Mode switch is the setting we ended up valuing most: off keeps 2D games crisp, so SNES and Genesis look right, while on smooths the polygons in N64 and Saturn titles. Pass-through mode digitizes the signal with no processing at all, and the physical on/off toggle is a small convenience we came to rely on when swapping cables behind a TV.

Latency deserves a test rather than a promise. The design is meant to add none, and on a 240p source it feels that way; composite from an N64 is where delay can appear, so run the games where timing matters before the return window closes. The unit itself is about 4.3 inches wide and vanishes behind the TV, which is exactly where you want it.

Pros

  • Composite and S-video inputs for unmodified consoles
  • Simple plug-and-play with a physical on/off toggle
  • Filter and pass-through modes for 2D and 3D games
  • Tiny footprint that hides behind the TV

Cons

  • Output tops out at 480p
  • No 4:3/16:9 switch, so the TV handles aspect
Our verdict

If your consoles only offer composite or S-video, this is the one to get: it takes signals nothing else here accepts and puts them on HDMI without a mod.

The mClassic needs an HDMI signal before it can do anything, so it's the wrong first purchase for a shelf of composite-only consoles. Feed it a digital picture, though — a docked Switch, a GameCube with an HDMI adapter, a PS2 already running through a converter — and it does something none of the analog boxes here can: it processes the image rather than just cleaning up the signal.

The processing is the product. Instead of repeating scanlines, it upscales to 1080p or 1440p and applies anti-aliasing across polygon edges in real time. Retro Mode, Mode 3, is the setting for classic 3D consoles; Mode 2 sharpens widescreen Switch play; Mode 1 passes the signal through untouched, so the puck can stay inline when you don't want it working.

On a 3D game the effect is easy to see and easy to like: jagged edges soften, distant textures stop shimmering, and an N64 or GameCube title looks closer to how you remember it than to how it actually looked. On 2D pixel art the case is much weaker, because the smoothing that flatters polygons is the last thing a crisp SNES sprite needs, and anything already at 1080p or above sees little. That split is why it sits below the OSSC and the GBS-C for us.

Two practical notes. Fitting one into a Switch dock takes an extension cable, since the body won't clear the recess — a small annoyance that turns into a daily one. And watch for output integrity: flickering white lines and brief dropouts can appear depending on the display, so run a long session on your own TV while you can still send it back.

Pros

  • Smooths jagged edges on 3D consoles
  • Three modes, including a clean pass-through
  • Light enough to leave inline permanently

Cons

  • Needs an HDMI source; not a converter
  • Switch dock needs an extension cable to fit
Our verdict

Buy it for a retro setup that already ends in HDMI and wants smoother 3D edges; for analog consoles you need a converter first, which is why it isn't our top pick.

How We Tested These Upscalers

We started by pulling together every upscaler still in production that supported more than one legacy input, which cut the field to about 30. From there we filtered by what the hardware accepts — composite, S-Video, component, SCART, HDMI — and by output resolution, since a box that can't hand your TV a clean 1080p or 4K signal is only solving half the problem. Ten made the cut, and we bought each one at retail so nothing arrived pre-tuned by a manufacturer.

Each unit spent seven months in rotation across two setups: a 4K living-room panel and a small CRT kept as a reference for what the original signal is supposed to look like. We measured latency with a high-speed camera pointed at the screen, capturing the gap between a button press and the pixel changing, then played through the same sections of fast, timing-dependent games to see whether that number was something your hands could feel. We also handed each one to someone who had never used an upscaler, with the manual face-down, and timed how long it took them to get a stable picture.

On the picture side, we fed every box the same test patterns and looked for shimmer on scrolling backgrounds, smeared text in menu screens, and colors that drifted warm or green. We wiggled each connector to see whether the ports were anchored to the board or just the plastic shell, and left every unit running four-hour sessions to check how hot the case got. Appearance got a fair hearing too — each one sat on an open shelf beside a stack of old consoles for a week. Value was the last call: what you actually get for the money against the other nine.

How to Choose a Retro Console Upscaler

Match the input to your consoles first

Every upscaler here accepts a different slice of the analog world, and none of them covers all of it. RGB SCART is the cleanest signal a stock retro console can produce, but only some machines offer it: an unmodified N64, a non-RGB NES and an NTSC GameCube don't. The Kaico OSSC is built for that RGB world, while the Mcbazel GBS-C adds component and VGA for a PS2, Xbox, Wii or a Dreamcast over VGA. Composite and S-video sit at the bottom of the ladder and only the RetroScaler2x takes them. Work backwards from the socket on your console.

The trap is buying the most capable box and discovering half your shelf can't feed it. Count your consoles by output type before you spend anything; if the answer is a mix, plan for two devices or accept that some machines stay on the shelf.

Line multiplication versus a straight 2x conversion

A 2x converter takes 240p to 480p and stops there. That's enough to get a picture onto a modern TV and to stop the set's own scaler from smearing it, but on a 4K panel the television still handles the final stretch. A line multiplier goes to 4x, 5x or 6x, which maps 240p much closer to a whole multiple of the panel and keeps pixels square and sharp. If your library is 2D and arcade-heavy, that sharpness is worth paying for. If you mostly want the old consoles playable in the living room, a 2x box does the job.

Take 480i seriously if you play PS2-era games

Interlaced 480i is where cheap scalers fall apart. Handling it by discarding alternate fields produces the flicker and jitter that makes a long session unbearable, while motion-adaptive deinterlacing reads the movement in each frame and rebuilds a stable progressive image. If your consoles are PS2, Saturn or Dreamcast, this matters more than the maximum multiplier, which is why we point those buyers at the GBS-C rather than at a sharper 240p-only box.

Budget for cables, power and an evening of setup

None of these arrives with the cable that gets the best out of them. A thin unshielded RGB SCART or component lead blunts the picture the scaler is working so hard on, so factor a decent one into the cost, and check whether a power supply is in the box before you're hunting for one. Then give yourself an evening: menus are deep, instructions are thin, and the gap between a good and a bad setting is often a single toggle.

Frequently Asked Questions

Final Verdict

For anyone with RGB-capable consoles, the Kaico OSSC 1.8 is the one we recommend without much hesitation: the sharpest 240p in this group, no lag worth worrying about, and the 1.8 firmware that makes it the revision to buy.

The exception is a library that leans on PS2, Saturn or Dreamcast, where the Mcbazel GBS-C's deinterlacing does more for the picture than extra line multiplication. And if your consoles only offer composite or S-video, start with the RetroScaler2x, because nothing else here will take the cable you already own.
