Starting off with a kernel plugin for the PlayStation Vita, cuevavirus/Marburg of Team CBPS has released yet another plugin for the console and this time around, it’s called PSOneScrot. As its name suggests, this plugin allows you take screenshots of PlayStation 1 games properly as pressing the PS Button+Start results in the taking of messed up screenshots.
To take a screenshot of a PS1 game with this plugin installed, all you have to do is open the Official Settings Menu by holding the PS Button and select ‘Screenshot’ which takes a screenshot of what’s on-screen for you. The plugin also comes with support for Adrenaline although to use it, you have to first open Adrenaline’s Quick Menu then navigate to the Official Settings Menu from there.
You may grab PSOneScrot from Team CBPS’ forum and install it in the *KERNEL section of your taiHEN config.txt. The source code can be found in this GitHub repository where you can also report bugs.
