PS Vita VPK Editor [UPDATE 1.2]
Hey there folks, I decided to make a simple cross-platform application to help users modify their VPK files thematically. My VPK Editor was designed to help you change up the graphic assets of your VPK’s livearea/icon.
- Opens any VPK file designed for the PS Vita
- Let’s you change the icon, the livearea icon, and the livearea background image
- Automatically converts the images (from JPEG or PNG) to the correct bit-depth (8 bit) supported by the PS Vita
- Mai Dump ZIP support
- Fixed squared window bug. (uses a widescreen friendly window size)
- Added basic support for modifying the template XML
If there’s enough interest, I’ll continue to work on adding more features to it (like editing the template.xml with your own text).
- Added Mai Dump ZIP support. You can now change the graphics of VPK’s and Dumps!
