The PlayStation TV, also known as PS TV, is a versatile little device that can bring your favorite PS Vita, PSP, and PlayStation classics to life on your TV screen. However, its native resolution scaling isn’t perfect, leading to subpar visual quality. That’s where Sharpscale comes in. This homebrew plugin allows you to enhance your PS TV’s video output for better visuals, offering native rendering resolutions and sharp, crisp graphics.
If you’re ready to upgrade your PS TV experience, this step-by-step guide will walk you through installing Sharpscale. With minimal effort, you’ll optimize your PS TV for a stunning display in no time.
What is Sharpscale?
Sharpscale is a user-developed plugin for the PS TV that bypasses the default scaling methods and outputs video in native resolution. This significantly improves visual clarity, making it ideal for avid gamers and retro enthusiasts. It supports custom resolutions such as 960×544 (native PS Vita resolution) and 720p HDMI output, providing crystal-clear visuals.
Before proceeding, bear in mind that installing Sharpscale requires a modded or homebrewed PS TV. If your PS TV is not modded, search for tutorials on how to homebrew your device before following this guide.
Step-by-Step Guide to Installing Sharpscale
Step 1: Ensure Your PS TV is Ready
Before you start, ensure that your PS TV is modded and running HENkaku or enso, which are required to install plugins like Sharpscale. Verify that you have VitaShell installed, as you’ll need it to manage files on your device.
- Tip: If your PS TV is not yet running HENkaku or enso, search for resources to install these essential tools before proceeding with this guide.
Step 2: Download the Sharpscale Plugin
The Sharpscale plugin file is required to begin the installation. Here’s what to do:
- Using your computer, visit a trusted homebrew website (such as GitHub) to download the Sharpscale plugin.
- Ensure you download the latest version of Sharpscale for compatibility and improved features.
- Extract the downloaded file if it is in a compressed format such as .zip or .rar.
Keep the extracted plugin file ready for transfer in the upcoming steps.

Step 3: Transfer Files Using VitaShell
Next, transfer the Sharpscale plugin to your PS TV using VitaShell. If you haven’t used VitaShell before, don’t worry—it’s straightforward.
- Open VitaShell on your PS TV.
- Connect your PS TV to your computer via USB or FTP (depending on your setup).
- Locate the folder named
ur0:tai/
orux0:tai/
on your PS TV. - Copy the Sharpscale plugin file (sharpscale.skprx) into the
tai/
folder.
Ensure the file is correctly placed to avoid installation issues.
Step 4: Edit the Config.txt File
Once the plugin file is in the correct directory, you’ll need to edit the plugin configuration file:
- In the same
tai/
folder, locate theconfig.txt
file. - Open the file using VitaShell’s built-in text editor.
- Under the
*KERNEL
section, add the following line:
ur0:tai/sharpscale.skprx
Note: Use ux0:
instead of ur0:
if that’s where you placed the plugin file. Save your changes and exit.
Step 5: Restart Your PS TV
For the changes to take effect, restart your PS TV. You can do this by holding down the power button and selecting Restart from the menu.
After the reboot, Sharpscale should be active, and your PS TV will utilize the plugin’s enhanced resolution scaling.
Step 6: Configure Sharpscale Settings (Optional)
Sharpscale comes with configurable options for adjusting resolutions and settings. You can access these features by installing the companion application for Sharpscale. Once installed, you can fine-tune the settings to suit your preferences and display hardware.
Enjoy your improved gaming and visual experience on your PS TV!
