Use circles, text and screen edges to judge display scaling, distinguishing useful enlargement, stretched proportions and controls obscuring the picture.

A small-looking picture in Yearn may reflect a mismatch between the phone and original console's aspect ratios, or space occupied by virtual controls. Establish what you want to enlarge before changing picture size, so that larger text does not push status information and controls against the screen edges.

## Choose a fixed scene that is easy to compare

Open a working game and stop at a menu containing title text, circular shapes and a border. Text helps assess sharpness, circles reveal horizontal stretching, and the surrounding border shows cropping. Compare the same scene where possible rather than drawing conclusions from two screenshots with differently sized characters.

Record the current orientation, whether a physical controller is connected, and whether touch buttons appear. All affect available space. If the picture shifts when a controller connects, first check whether virtual controls hide with the connection state, then investigate scaling. This avoids mistaking an ordinary layout change for a display fault.

## Distinguish aspect ratio from picture size

Picture size determines how much space the same image occupies; aspect ratio determines its width-to-height relationship. Proportional enlargement keeps circles round and characters' proportions intact. Widening only horizontally makes characters broader and changes spacing between text strokes. A wide phone screen does not mean the game needs to cover every part of it.

Consoles do not all share one original aspect ratio. Handhelds, home consoles and dual-screen systems can naturally leave different borders on the same phone. Judge proportions using known in-game shapes before deciding to enlarge the picture. This is more reliable than judging quality from border width alone.

## Change one scaling setting at a time

In Yearn's display settings, find Picture Size or Scale, following the labels actually shown on your device. Record the current value, increase it slightly, and return to the fixed comparison scene. Check top status information, bottom text and both sides before deciding whether to enlarge it further.

Inspect all four edges after every change. Important information is not always central: speedometers, character status and notes below menus may sit at the edges. An enlarged central character is easy to notice, while a missing corner line may remain unnoticed until play. Checking edges after each adjustment reduces repeated resets.

## Use empty space for the controls

With touch controls, empty space keeps fingers and virtual buttons away from important content. Try your normal grip and watch whether your thumbs often obscure a character or dialogue. A slightly smaller picture with reliably reachable directional controls is often easier to use than a completely filled screen.

If the buttons are too large or opaque, adjust virtual-controller size and transparency separately. Shrinking the entire game to solve every control overlap also sacrifices text legibility. Check picture completeness and ease of control as separate questions to find the setting that actually needs changing.

## Recheck landscape orientation and a physical controller separately

After adjusting portrait mode, rotate the device and view the same scene again. Landscape offers different available width and height, so a scale that suits portrait may not suit it. Check system orientation lock before deciding whether the layout failed to change or the app is using a landscape layout while retaining the content's aspect ratio.

Check the edges and center again after connecting a physical controller. Hidden touch controls may make a larger picture preferable, but retain the complete content. For dual-screen platforms such as NDS, inspect both displays separately. If one is clear and the other too small, address the dual-screen layout before enlarging everything.

## Keep a simple record of your choices

In Notes, record five items: device, orientation, platform, picture size and controller state. Add an observation, such as portrait touch controls with readable subtitles and complete bottom notes, or landscape with a physical controller and side borders without distortion. This is more useful than a slider value alone because the same value may look different on another screen.

To restore a setting, first return to the original orientation and controller state, then restore its value. Matching the scene conditions makes comparison fair. Screenshots help, but enlarged viewing in Photos changes their apparent size. Also check the actual play view on the phone.

## Questions and final checks

**Edges look stair-stepped after enlarging. Is the setting wrong?** Older games' pixel edges become more visible at larger sizes. Distinguish the original pixel style from stretched proportions and cropping before reducing scale. Increasing display size alone cannot add detail absent from the original game.

**Why do black borders remain?** When the game and phone have different aspect ratios, showing the complete picture normally leaves empty space. Filling the screen may require cropping or stretching, so decide which result matters more. A complete picture is usually easier to verify in games with information in their corners.

Return to real gameplay: move continuously, open menus and read some text. Check portrait and landscape. Once the main content is complete, character proportions look natural and controls are easy to reach, use these settings as a starting point for everyday play. Repeat the comparison for a different console's picture later.
