{{#seo: |title=Vita Homebrew Apps (Plugins) - GameBrew |title_mode=append |image=sharpscalevita2.png |image_alt=Sharpscale }} 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, it 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. If the config app crashes on startup, follow these steps: *Use the plugin and config app attached to this post. *Ensure that the plugin is loaded. It will be immediately noticeable on startup if it is loaded. *Disable plugins for the config app by adding the following line. *!AKRK00005 before this line in the taihen config.txt *ALL ==Screenshots== https://dlhb.gamebrew.org/vitahomebrews/sharpscalevita3.png ==Media== '''Sharpscale demo: direct HDMI capture with native 960x544''' ([https://www.youtube.com/watch?v=SRJV9iP2tkY marburg]) <br> <youtube>SRJV9iP2tkY</youtube> '''Sharpscale demo: 960x544 in 720p integer scaled to 1440p''' ([https://www.youtube.com/watch?v=VJp6swTU3SA marburg]) <br> <youtube>VJp6swTU3SA</youtube> ==Changelog== '''v1.5.0 2020/06/13''' * Texts in the configuration app has been changed for clarity. * Configuration app has a manual that can be opened from the LiveArea. * kernel plugin does not need to be updated. '''v1.4.0 2020/06/09''' * Allow enable HD framebuffer sizes on the Vita. * Add HD resolutions to scaling test. * Fixed crashes in config app. * Bilinear filtering reverts to system default whenever scaling is not applied. '''v1.3.0 2020/05/05''' * Added an option to enable large framebuffer sizes, when the application uses large framebuffers. '''v1.2.0 2020/04/24''' * Added options for PS1 aspect ratio modes. * Added fitted scaling mode. * Added config application (ur0:/data/sharpscale/config.txt no longer needed). '''v1.1.1 2020/04/09''' * Fixed a bug where some PS1 games had black screen in 1080i. * Centred the framebuffer when cropping occurs. * Enabled "display area settings" in original mode. '''v1.1.0 2020/04/06''' * All framebuffer sizes are now supported and there are now two configurable options, scaling mode, and bilinear filtering. Configuration is provided by a text file at ur0:/data/sharpscale/config.txt. ==External links== * Author's website - https://bin.shotatoshounenwachigau.moe/vita/sharpscale/ * CBPS Forums - https://forum.devchroma.nl/index.php?topic=112.0 * Reddit - https://www.reddit.com/r/vitahacks/comments/fw87e4/release_sharpscale_native_resolution_output/
