Display Issues

Sakura renders games at their native resolution by default and lets you adjust scaling and sharpening on top of that. If something looks off, start here.

Cause: Most NScripter/ONScripter games run at a low native resolution designed for old PC monitors, so on a modern high-density screen the art can look soft when scaled up.

Solutions:

1. Open Settings > ONScripter Engine (or per-game Game Settings, if Use Global Settings is off) and raise Render Scale to 2x or 3x. This supersamples the game at a higher internal resolution before scaling it to your screen. This takes effect at the next launch, not live.
2. Try the Upscale Filter options — Smooth (linear, the default), xBRZ (an edge-preserving upscaler that suits pixel art), or Sharp. This one applies live to a running game, both from Settings and from the in-game overlay’s Settings window (“Upscaling”).
3. Add some Sharpen (CAS) — contrast-adaptive sharpening, 0–100%, default 0 (off). This also applies live, via the overlay’s “Sharpen” slider or the global/per-game setting. It’s meant to crisp up soft, low-resolution art without a full re-render.

If you’ve been experimenting with Render Scale, Upscale Filter, or Sharpen and want to get back to a known-good state:

• Render Scale → 1x (native, no supersampling)
• Upscale Filter → Smooth
• Sharpen (CAS) → 0% (off)

Set these in Settings > ONScripter Engine for the global defaults, or in a game’s Game Settings if it has Use Global Settings turned off (its per-game override needs to be reset there instead — turning “Use Global Settings” back on will make it follow the global values again).

Cause: NScripter/ONScripter games are built for a fixed design resolution and aspect ratio. When that doesn’t match your device’s screen, Sakura letterboxes the game (fits it to the largest size that preserves its original aspect ratio) rather than stretching or cropping the art.

This is expected behavior, not a bug — stretching would distort the original artwork, and Sakura prioritizes showing the game as it was designed to look.

Cause: This is very likely not the game rendering — it’s the Icon-Colored Game Pages setting, which tints a game’s own library/detail page (and its bubble particles) using colors sampled from its icon. It doesn’t touch the game’s actual rendering.

Solution: Go to Settings > General and turn off Icon-Colored Game Pages if you’d rather every game’s page use a neutral look.

If a game’s actual in-game rendering looks broken (not just soft or tinted) — for example, corrupted sprites or backgrounds — that’s most likely an issue with the archive itself rather than a display setting; see Import Problems to check whether it extracted cleanly, or reach out via Support.
