Over the Holiday break frangar released Oclock Vita a simple taiHEN plugin for overclocking your PSVita or the PSTV. He has also added support for games to be decrypted and encrypted, this means we no longer have to dump our games just to overclock them.
Put “oclockvita.suprx” in ‘tai’ folder in the root of your Vita.
Change config.txt in that directory to load plugin for title of your choice by adding new lines like below:
# titleid for your game (this one is for Root//Letter for example) *PCSB01019 ux0:tai/oclockvita.suprx
After that just run the game and press SELECT + UP to enable menu. Press SELECT + DOWN to close menu.
