Use Pixel Perfect instead of 4:3 when perfectly square pixels and maximum edge crispness matter more than the familiar original-console framing. On a modern 16:9 television, do not stretch the game to fill the screen unless you deliberately prefer distorted, wider sprites.
The right setup depends on whether you are using a Nintendo SNES Classic, Nintendo Switch, an emulator, or original SNES hardware through an HDMI converter. The display principles are the same, but the menus and controller tools differ. The settings below separate those choices so you can reproduce the look and controls you want without trial and error.

The best settings at a glance
Recommended starting point: select 4:3 for the image, keep your television in its normal game/low-processing picture mode, and use an SNES-style gamepad. This preserves the proportions and hand positions most players associate with A Link to the Past. Change only one setting at a time while comparing a static scene with text, diagonal terrain and Link’s sprite.
| What you value most | Display choice | Controller choice |
|---|---|---|
| Familiar original-console framing | 4:3 | SNES-style layout with the original face-button and shoulder positions |
| Sharp, geometric pixels | Pixel Perfect | SNES-style layout; map by physical position on other pads |
| Soft, scan-lined television appearance | CRT Filter | SNES-style layout; avoid extra button changes until the picture is comfortable |
| Portable or desktop play | 4:3 or integer-scaled Pixel Perfect, depending on the emulator | Built-in pad, USB pad or compatible wireless pad with the same layout |
These are presentation choices rather than performance ratings. There is no single objectively correct filter. The best option is the one that keeps circles, characters and text looking intentional on your particular screen.

What Nintendo’s three display modes actually change
Nintendo’s SNES Classic support documentation identifies three presentation modes: 4:3, Pixel Perfect and CRT Filter. They change the geometry and visual treatment of the same game image; they do not alter the game’s rules or artwork.
4:3: the safest default
4:3 recreates the familiar SNES-era screen shape with a slight horizontal stretch. On a 16:9 television, the image remains a centered rectangle with vertical side bars rather than occupying the entire panel. This is the most broadly comfortable setting if you remember the game from an original console or want the least visually surprising result.
Choose 4:3 when you want the map, menus and character proportions to resemble a conventional living-room setup. If a television has its own aspect-ratio control, leave the console or emulator at 4:3 and avoid applying a second stretch at the display. Double-scaling can make edges uneven and may widen the picture more than intended.
Pixel Perfect: square pixels and hard edges
Pixel Perfect prioritizes pixel geometry. Nintendo describes it this way: “Pixel Perfect: Each pixel is a perfect square, so you see the games exactly as designed.” The result is a cleaner, more grid-like image, with crisp corners on text and sprites.
Pixel Perfect can appear smaller than a television-filling image because preserving square pixels does not always fill a modern panel evenly. That is expected. Select it if you prefer sharp, discrete blocks and do not mind larger side borders or a less “television-like” presentation. It is particularly useful when a CRT effect looks too soft or when text is your main concern.
CRT Filter: scan lines and a softer character
CRT Filter adds scan lines and a presentation modeled on an older tube television. It softens hard digital edges and can make flat-color areas appear less stark on a bright modern panel.

Use CRT Filter if you specifically want that analog character. It is not a resolution upgrade, and it will not make a modern LCD behave exactly like a particular tube set. If scan lines make text difficult to read from your seating distance, return to 4:3 or Pixel Perfect rather than compensating with excessive television sharpness.

How to set up a modern TV without stretching the game
Start at the source device, then check the television. The source should make the primary aspect decision; the TV should display that signal without adding another crop or stretch.
Recommended television checks
- Open the TV’s picture or aspect-ratio menu and choose an option that preserves the incoming 4:3 image. Names vary by manufacturer; look for “4:3,” “Original,” “Just Scan,” “Screen Fit” or an equivalent setting that does not zoom.
- Turn off overscan if the television offers a “fit to screen” or “1:1” option. Overscan can hide the outermost pixels and make menus appear clipped.
- Use the set’s game or low-processing picture mode when available. This avoids unnecessary motion smoothing and image enhancement that can make a two-dimensional game look unstable.
- Set sharpness near the display’s neutral midpoint instead of turning it up to maximum. Artificial edge enhancement can create halos around text and diagonals.
- Disable motion interpolation, noise reduction and dynamic contrast for this source if those controls visibly alter solid-color backgrounds or scrolling.
- Stand or sit at your normal playing distance and inspect text, diagonal walls and Link’s outline. If the picture is wider than expected, correct the aspect setting at the TV before changing the game mode.
Menu names and available controls differ by television model, so do not assume that a setting called “wide” is harmless. A mode that fills the 16:9 panel usually stretches the 4:3 image.
Choosing settings on a Nintendo SNES Classic
The SNES Classic presentation options are the clearest reference for the three looks: 4:3 for the original-style frame, Pixel Perfect for square pixels and CRT Filter for scan lines. Open the console’s game display options, preview each mode on a scene containing text and diagonal lines, and keep the one that remains comfortable after several minutes.
A practical SNES Classic sequence
- Launch A Link to the Past and open the console’s game or display settings.
- Select 4:3 first and confirm that the television is not applying a second zoom.
- Compare Pixel Perfect from the same scene. Check whether the sharper edges improve readability or instead make individual pixels distracting.
- Try CRT Filter only if you want scan lines and a softer image. Check small menu text before committing.
- Save the setting, then play through a short area with scrolling, menus and combat. A mode that looks impressive on a still screen may be tiring during movement.
The mode does not change the game’s controls, saves or difficulty. It is safe to switch when you want a different presentation.
Emulator settings for computers, phones and other devices
Emulators expose more options than Nintendo’s preset modes, so the goal is to reproduce the same trade-offs without stacking conflicting filters.
Rank #3
- Wired Controller, USB cable: 1.8M.
- Compatible with Switch (version 3.0.0 or above), Windows, Raspberry Pi devices.
- Rumble vibration.
- Support turbo function.
Set the aspect ratio first
- Open the emulator’s video settings and choose a 4:3 aspect option, or an integer-scaling option that preserves the original proportions.
- Disable “stretch to fit,” “fill screen” or similar 16:9 modes unless you consciously want wider sprites.
- If the emulator offers separate horizontal and vertical scaling, enable integer scaling for the cleanest Pixel Perfect-style result. Accept the unused border area rather than rounding one dimension unevenly.
- Choose either a clean pixel shader or a CRT-style shader. Do not enable several sharpening and scan-line effects at once; combined processing can obscure text.
- Save a per-game profile so another title’s widescreen preference does not change A Link to the Past.
Emulator labels differ, but the decision remains the same: preserve 4:3 geometry, then choose between hard square pixels and a softer CRT treatment. If a shader includes curvature, vignette or simulated glare, those are optional aesthetic effects rather than requirements for accurate proportions.
Window size and readability
A very small Pixel Perfect window can make menu text uncomfortable. Increase the integer scale or move the window closer before abandoning square pixels. If no integer size fits your monitor, 4:3 with a modest non-integer scale may be easier to read than a tiny perfectly scaled image. Keep the emulator’s frame centered and avoid a television zoom that crops the borders.
Connecting original SNES hardware to a modern display
Original hardware normally needs a television input that accepts its signal or a separate retro HDMI upscaler. The useful target is still a stable 4:3 image; the converter should not force a 16:9 stretch.
Connection checklist
- Connect the console to the scaler or compatible display input according to the device’s manual.
- Set the scaler’s output or aspect control to 4:3, not full-screen widescreen.
- On the television, select the input’s game/low-processing mode and disable overscan if possible.
- Inspect the first screen for cropping, shimmer and excessive softness before changing any other control.
- If the scaler offers integer scaling, compare it with a normal 4:3 scale. Integer scaling may produce larger borders but keeps pixel blocks uniform.
Different scalers have different processing paths. This guide does not assign a latency value to any model, so choose a unit based on its documented compatibility and controls rather than an unverified speed claim.
Keep the controller layout close to the SNES pad
A Link to the Past was designed around a four-button diamond and two shoulder buttons. Preserving that physical relationship is more valuable than matching the printed letters on a modern controller.
| Game function | SNES position | Recommended modern mapping principle |
|---|---|---|
| Primary sword/action button | Right face button | Use the face button in the same physical position as the SNES right button |
| Secondary item/action button | Lower face button | Use the lower face button so the thumb can roll naturally from the primary action |
| Map and pause functions | Left and top face buttons | Keep these positions consistent with the original diamond |
| Shield, item or shoulder functions | Left and right shoulder buttons | Map to the corresponding left and right shoulder controls |
| Movement | Directional pad | Use a digital D-pad when possible; an analog stick is an alternative for players who prefer it |
When a controller’s labels differ from Nintendo’s, ignore the letters and map by location first. That keeps muscle memory intact when you switch between platforms.

Remapping on Nintendo Switch
Nintendo provides a system-level remapping feature for compatible controllers. The documented path is System Settings → Controllers and Sensors → Change Button Mapping.
Free tools Windows power users keep installed
One-click scans. No signup required.
- From the Switch HOME menu, open System Settings.
- Select Controllers and Sensors.
- Choose Change Button Mapping.
- Select the controller and button you want to change.
- Assign the desired function, review the on-screen summary and save.
- Launch the game and test movement, the two face-button actions and both shoulder buttons before starting a long session.
Nintendo states that custom mappings are saved on the Switch system. Remember that a remap can affect other games using that controller; restore the original arrangement when you want each title’s default layout.
Using an 8BitDo SN30 Pro
The 8BitDo SN30 Pro is an SNES-style controller option. Its official FAQ documents compatibility with Nintendo Switch, Windows 10, macOS, Android and Raspberry Pi, as well as USB connection. That makes it suitable for a living-room console, a computer emulator or a supported mobile setup, provided your device and operating system recognize the controller in the mode you select.
Connection and mode choices
- Switch: pair the controller using the Switch-compatible mode described in the controller documentation, then verify the buttons in the system controller menu.
- Windows, macOS, Android or Raspberry Pi: use the documented wireless or USB procedure for that platform and confirm that the operating system sees the device before opening the emulator.
- Steam: the FAQ documents a “Nintendo button mapping” mode. Use it when you want the on-screen Nintendo arrangement to correspond to the physical SNES-style positions.
USB is useful when you want a direct wired connection or when wireless pairing is inconvenient. The compatibility information does not establish a measured latency advantage for USB or wireless, so choose based on reliability, cable reach and comfort rather than an unsupported performance promise.

Configure the gamepad in the emulator’s input menu, then test every function in a safe area. Mapping by physical position avoids the common mistake of assigning actions according to the letters printed on an Xbox-style or third-party pad.
- Open the emulator’s controller configuration for player one.
- Select the D-pad and press the corresponding directions on the physical controller.
- Map the four face buttons by position: right, lower, left and top. Assign the game’s functions according to the original SNES arrangement.
- Map the left and right shoulder buttons to the matching physical shoulders.
- Leave emulator hotkeys such as save-state, fast-forward and menu access on separate buttons or a modifier combination. Do not place them where an accidental press could interrupt combat.
- Save a game-specific profile and test movement, menu navigation, item use and both shoulder actions.
Convenience hotkeys are optional. The priority is a dependable layout that never competes with an in-game command.

Platform-by-platform recipes
| Platform | Display setup | Controller setup | Best use case |
|---|---|---|---|
| SNES Classic | Start at 4:3; compare Pixel Perfect and CRT Filter from the built-in display choices | Use the included SNES-style pad or another pad mapped by physical position | Simple television play with no emulator configuration |
| Nintendo Switch | Keep the console’s game image at its intended proportions and prevent television zoom | Use the default layout or remap through System Settings → Controllers and Sensors → Change Button Mapping | Portable or docked play with system-level remapping |
| Desktop emulator | 4:3 or integer scaling; choose one clean-pixel or CRT shader | Map by physical position, then isolate hotkeys | Fine control over scaling, profiles and filters |
| Original SNES plus HDMI converter | Set the converter and TV to 4:3; disable overscan where available | Use an original or SNES-style pad | Authentic hardware with a modern display connection |
Troubleshooting common picture problems
The image fills the screen and Link looks too wide
Set the source and television to 4:3 or an equivalent original-aspect option. Check both devices; one may be stretching an already-correct signal.
Text or outer edges are cut off
Disable overscan or choose “fit to screen,” “just scan” or the manufacturer’s equivalent. Check the scaler as well as the TV, because either device can crop the image.
Pixel Perfect looks tiny
Increase the integer scale or sit closer rather than switching to a stretched widescreen mode. If your display cannot show a comfortable integer size, use 4:3 with moderate scaling.
Recommended Free Tools
CRT Filter is too dark or distracting
Return to 4:3 or Pixel Perfect. Scan lines are an aesthetic option, not a requirement. Also check that the television’s own contrast, sharpness or noise-reduction controls are not exaggerating the filter.
The controller works in menus but not in the game
Open the emulator or console’s game-specific input profile and remap player one. Confirm that the correct controller mode is active, especially after switching between wireless and USB connections.
Buttons feel “wrong” despite being labeled correctly
Remap by physical position instead of letter. A controller that swaps Nintendo’s A/B or X/Y labeling can still feel natural once the right, lower, left and top positions match the SNES arrangement.
A final setup checklist
- Picture is centered and visibly 4:3, not stretched to 16:9.
- Overscan and unnecessary motion processing are disabled for the game input.
- You chose one visual priority: familiar framing, square pixels or CRT scan lines.
- Text is readable at your normal seating distance.
- The D-pad and four face buttons follow the SNES physical positions.
- Both shoulder buttons are mapped and easy to reach without shifting your grip.
- Emulator hotkeys are separated from in-game actions.
- Switch remapping, when used, is saved and recorded so you can restore it later.
- An 8BitDo SN30 Pro or other replacement pad is connected in the correct platform mode and tested before play.
If you are unsure, revert to 4:3 and the original SNES-style layout. Those choices provide the most predictable baseline; Pixel Perfect, CRT Filter and remapped controls can then be added one at a time to match your preference.
