pngshot is a plugin to make screenshots great again.
Takes screenshots in png format
Take screenshots in any app
Copy pngshot.suprx to ur0:tai and add ur0:tai/pngshot.suprx below *main in ur0:tai/config.txt.
Note that this was only tested with retail SceShell. If, for some reason, you have some weird modifications done to your SceShell, this plugin will probably crash your Vita.
Press PS button + Start to take a screenshot. You can access screenshots with the Photos app, or from ux0:picture/SCREENSHOT.
