Sharpscale is a PSTV and PS Vita plugin that changes the framebuffer to display scaling method to provide a cleaner and sharper image.

This plugin is the only method to obtain native resolution video capture with accurate colours at 60fps. A hardware capture kit for the Vita was previously available from Japan for $450 USD, but due to changes in Japanese laws, this is no longer available.

Installation

Place the sharpscale.skprx to your tai folder in ur0.

Modify ux0:tai/config.txt and insert the path to the plugin

*KERNEL
ur0:tai/sharpscale.skprx

The configuration app sharpscale_config.vpk can be installed with VitaShell.

User guide

Sharpscale can be configured to different scaling methods.

Scaling Modes:

• Original - System default.
• Integer - Integer scaling while fitting inside the display, for general use with bilinear filtering off.
• Real - No scaling, for video capture.
• Fitted - Non integer scaling fitting exactly inside the display while preserving aspect ratio, for media use with bilinear filtering on, or PS1 with bilinear filtering off.

PS1 aspect ratio:

• Pixel - Aspect ratio of the framebuffer is retained.
• 4∶3 - Aspect ratio is forced to 4∶3.
• 16∶9 - Aspect ratio is forced to 16∶9.

Scaling algorithm:

• Point - Nearest neighbour.
• Bilinear - Bilinear interpolation (system default).

In Adrenaline, set graphics mode to original in Adrenaline settings.

Unlock framebuffer size:

• On - Allow framebuffers of sizes 1280x720, 1440x1080, and 1920x1080 to be used.
• Off - System default.

Configuration

Use the provided configuration app to change settings instantly without needing to close the foreground application or needing to reboot.
