Video filters and screen layouts
Parlor renders through Metal with three filters, four Game Boy palettes, optional color correction and integer scaling — and, for the DS, a layout panel you can adjust while the game keeps running.
Screen filters
| Filter | Look |
|---|---|
| Sharp (default) | Crisp pixels, no processing |
| LCD grid | A faint grid between pixels, like a backlit handheld |
| CRT soft | Gentle scanlines and bloom |
Set it in Settings → Screen filter or from the pause menu's gear; the change is instant.
Palettes and color
- Palette applies to original Game Boy games only: Grey, Game Boy green (default), Game Boy Pocket, Game Boy Light.
- Color correction (default on) reproduces how Game Boy Color games looked on the original LCD, which is softer than raw output. Turn it off for saturated colors.
Scaling
By default the picture fills as much of the screen as its aspect ratio allows. Pixel-perfect scaling restricts it to whole-number multiples, so every game pixel is the same size on screen, at the cost of a border.
On the Mac, the Size menu resizes the window to exactly 2×, 4×, 6× or 8× pixels (⌘1 to ⌘4). See Mac.
Dual-screen layouts
For Nintendo DS (and 3DS) games, tap the layout pill in the HUD. A floating panel opens over the running game.
| Mode | Extras |
|---|---|
| Stacked | Second-screen size, gap |
| Side by side | Second-screen size, gap, which side the touchscreen sits on |
| Corner | Corner size, which corner |
| One screen | Which screen to show |
Swap screens flips the two. Faster: two-finger double-tap the game.
Layouts are remembered per game, per device kind (phone, pad, TV, Mac) and per orientation, and sync to your other devices along with everything else.
Nintendo DS on a TV
When a DS game plays on a TV — Apple TV, AirPlay or an HDMI adapter — Settings → Nintendo DS on TV picks what the big screen shows: Top screen only (default), Both screens, or Both, side by side. Your iPhone shows the touchscreen live so you can still use it. See Nintendo DS.
