Thanks to the CBPS forum, the cuevavirus developer has released a new plugin update that solves the puzzle (a bounty organized by Rinnegatamante) of the native resolution on PSVITA TV called Sharpscale. Sharpscale offers the following two features:
- 720p: Generates the size of the native 960 × 544 framebuffer with black borders
- 1080i: scale the framebuffer to 1920 × 1088 and cut the bottom 8 lines
- Full scaling is therefore possible up to 1440p and 4k.
This is the only method for capturing native resolution video with accurate colors at 60 fps. A hardware acquisition kit for Vita was previously available from Japan for $ 450 USD, but due to changes in Japanese laws, this is no longer available. The resizing test program shows 1 pixel wide horizontal and vertical lines alternating between white and black. If patterns are observed, scaling was performed incorrectly, as in all output modes without this plugin.
Sharpscale has been updated with new features: all framebuffer sizes are now supported and two configurable options are now available.
Original: system default
Integer: scaling integer up to the maximum size suitable for display resolution
Real: no scaling is performed
Bilinear filter On
: system default
Off: nearest neighbor
Here are some recommended configurations for several cases:
Games: full bilinear off
Games with variable framebuffer size: original bilinear on
HDMI capture: real
Media: original bilinear activated
For adrenaline and PS1 games, disable any built-in resizing via the adrenaline options or the quick (official) menu options.
The configuration is provided by a text file in ur0: /data/sharpscale/config.txt containing two numbers separated by a space.
For example, to use full mode and disable the bilinear filter, write “1 0” in the text file.
- For installation, Autoplugin 2 is sufficient or manually as explained below:
- Download the file at the end of the article and insert it in the ur0: tai folder
- Add the following string in ur0’s config.txt file: tai as in the example below
ur0: tai / sharpscale.skprx
– Fixed a bug where some PS1 games had a black screen in 1080i
– Centered the framebuffer when clipping occurred
– Enabled “display area settings” in original mode
New version 2020-04-24
– Added PS1 aspect ratio options
– Adapted scaling mode
added – Configuration application added (ur0: /data/sharpscale/config.txt no longer needed)
