Have you added this "ux0:adrenaline/adrenaline.suprx" after the game you are using in the taihen config? Have you reloaded the config in the settings (Start button) of molecularshell?
For anyone that doesn't have a PSP game to use it on, use this: http://gekihen.customprotocol.com/en/project/ePSP-Bubble-Installer
It's way smaller than the available free demo's that you can use.
Don't use the leaked version. There is an official version coming out soon. The leaked version didn't work for every game anyway, there were a ton of broken games.
