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 ur0: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.
